Sulphuric Acid Essay, Research PaperSulphuric Acid Industry in OntarioAmong the many workss in Ontario where sulphuric acid isproduced, there are three major works locations that shouldbe noted on history of their greater size.

These are: ( 1 )Inco. & # 8211 ; Sudbury, ( 2 ) Noranda Mines Ltd. & # 8211 ; Welland, and ( 3 ) Sulfide & # 8211 ; OntarioThere are a figure of factors which govern the locationof each fabrication works. Some of these factors that haveto be considered when make up one’s minding the location of a Sulfuric Acid works are:a. Whether there is ready entree to raw stuffs ;B.

Whether the location is near to major transit paths ;c. Whether there is a suited work force in the country forworks building and operation ;d. Whether there is sufficient energy resources readily available ;e. Whether or non the chemical works can transport out itsoperation without any unacceptable harm to the environment.Listed above are the basic decision making factors that governthe location of a works. The followers will explicate ingreater item why these factors should be considered.

1 ) Raw MaterialsThe works needs to be near to the natural stuffs thatare involved in the production of sulphuric acid such asS, lead, Cu, Zn sulphides, etc..2 ) Transportation systemA maker must see propinquity to transpor-tation paths and the location of both the beginning of naturalstuffs and the market for the merchandise. The naturalstuffs have to be transported to the works, and theconcluding merchandise must be transported to the client ordistributer.

Economic pros and cons must besides be thoughtapproximately. For illustration, must sulfuric workss are locatednear the market because it costs more to transportsulphuric acid than the chief natural stuffs, S.Elaborate committee cogent evidence container are required for thetransit of sulphuric acid while S can be muchmore easy transported by truck or railroad auto.3 ) Human Resources For a sulphuric acid works to run, abig work force will evidently be required. The works mustemploy chemists, technicians, decision makers, computing machineoperators, and people in gross revenues and selling. A big figureof workers will besides be required for the day-to-day operation ofthe works. A work force of this diverseness is hence likelyto be found merely near major Centres of population.4 ) Energy DemandsLarge sums of energy will besides be required for theproduction of many industrial chemicals.

Therefore, propinquityto a plentiful supply of energy is frequently a findingfactor in make up one’s minding the works & # 8217 ; s location. 5 ) Environmental ConcernsMost significantly, nevertheless, concerns about theenvironment must be carefully taken into consideration.The chemical reaction of altering S and othersubstances to sulfuric acerb consequences in the formation ofother substances like S dioxide. This causes acidrain.

Therefore, there is a large job about sulfuricworkss doing harm to our environment as the works isa beginning of S emanation taking to that of acerb rain.6 ) Water SuppliesStill another factor is the intimacy of the locationof the workss to H2O supplies as many fabricationworkss use H2O for chilling intents.In add-on to these factors, these inquiries must besidesbe answered: Is land available near the proposed site at asensible cost? Is the clime of the country suited? Arethe general life conditions in the country suitable for thepeople involved who will be relocating in the country? Is at that placeany suggestions offered by authoritiess to turn up in a peculiar part?The concluding determination on where the sulphuric acid workstruly involves a careful scrutiny and a via media amongall of the factors that have been discussed above.Producing Sulfuric AcidSulphuric acid is produced by two chief procedures & # 8211 ;the chamber procedure and the contact procedure.The contact procedure is the current procedure being used togreen goods sulphuric acid. In the contact procedure, a purifieddry gas mixture incorporating 7-10 % S dioxide and 11-14 %O is passed through a preheater to a steel reactorincorporating a Pt or V peroxide accelerator.

Theaccelerator promotes the oxidization of S dioxide totrioxide. This so reacts with H2O to bring forth sulphuricacid. In pattern, sulfur trioxide reacts non with pureH2O but with recycled sulphuric acid.The reactions are: 2SO2 + O2 & # 8211 ; * 2SO3SO3 + H2O & # 8211 ; * H2SO4 The merchandise of the contact workss is 98-100 % acid. Thiscan either be diluted to take down concentrations or madestronger with sulfur trioxide to give oleums. For theprocedure, the beginnings of S dioxide may be produced frompure S, from fool’s gold, recovered from smelter operationsor by oxidization of H sulphide recovered from thepurification of H2O gas, refinery gas, natural gas and other fuels.

Battery Acid Industry Many industries depend on sulphuric acid. Among theseindustries is the battery acid industry.The electric battery or cell green goodss power by agencies ofa chemical reaction.

A battery can be primary or secondary.All batteries, primary or secondary, work as a consequence of achemical reaction. This reaction produces an electriccurrent because the atoms of which chemical elements aremade, are held together by electrical forces when they react to organize compounds.A battery cell consists of three basic parts ; apositively charged electrode, called the cathode, anegatively charged electrode, called the anode, and achemical substance, called an electrolyte, in which theelectrodes are immersed. In either a moisture or dry cell,sufficient liquid must be present to let the chemical reactions to take topographic point.

Electricity is generated in cells because when any ofthese chemical substances is dissolved in H2O, itsmolecules break up and go electrically charged ions.Sulphuric acid is a good illustration. Sulfuric acid, H2SO4, hasmolecules of which consist of two atoms of H, one ofS and four O.

When dissolved in H2O, themolecules split into three parts, the two atoms of Hseparate and in the procedure each loses an negatron, goinga positively charged ion ( H+ ) . The sulfur atom and the fouratoms of O remain together as a sulphate group ( SO4 ) , andget the two negatrons lost by The hydrogen atoms, thereforegoing negatively charged ( SO4 & # 8211 ; ) . These groups cancombine with others of opposite charge to organize other compounds.The lead-acid cell uses sulphuric acid as theelectrolyte. The lead-acid storage battery is the mostcommon secondary battery used today, and is typical of thoseused in cars.

The followers will depict both thebear downing and dispatching stage of the lead-storage batteryand how sulphuric acid, as the electrolyte, is used in theprocedure. The lead storage battery consists of two electrodesor home bases, which are made of lead and lead peroxide and areimmersed in an electrolytic solution of sulphuric acid. Thelead is the anode and the lead peroxide is the cathode.

Whenthe battery is used, both electrodes are converted to takesulphate by the undermentioned procedure. At the sulphate ion that isnowadays in the solution from the sulphuric acid. At thecathode, meanwhile, the lead peroxide accepts two negatronsand releases the O ; lead oxide is formed foremost, and solead joins the sulfate ion to organize lead sulphate. At the sameclip, four H ions released from the acid join theO released from the lead peroxide to organize H2O. Whenall the sulphuric acid is used up, the battery is & # 8220 ; discharged & # 8221 ;produces no current.

The battery can be recharged by go throughingthe current through it in the opposite way. Thisprocedure reverses all the old reactions and signifiers lead atthe anode and lead peroxide at the cathode.Proposed ProblemI ) The concentration of sulphuric acid is 0.0443 mol/L.The pH is: No. mol of H ions = 0.

0443 mol/L x 2= 0.0886 mol/L hydrogen ions pH = & # 8211 ; log [ H ]= & # 8211 ; log ( 0.0886 ) = & # 8211 ; ( -1.0525 ) = 1.05 Therefore, pH is 1.05.two ) The sum of base needed to neutralize the lake H2O is:volume of lake = 2000m ten 800m x 50m= 800,000,000 M3 or 8 & # 215 ; 108 M3since 1m3=1000L, hence 8 & # 215 ; 1011 L0.0443 mol/L x 8 & # 215 ; 1011 = 3.

54 ten 1010 mol of H2SO4 in H2O# mol NaOH = 3.54 ten 1010 mol H2SO4 x 2 mol NaOH1 mol H2SO4= 7.08 ten 1010 mol of NaOH neededMass of NaOH = 7.08 ten 1010 mol NaOH x 40 g NaOH1 mol NaOH= 2.83 ten 1012 g NaOH or 2.

83 ten 109 kilograms NaOHTherefore a sum of 2.83 ten 1012 g of NaOH is needed toneutralize the lake water.iii ) The usage of Na hydrated oxide versus limestone toneutralize the lake H2O:Sodium hydrated oxide: Sodium hydrated oxide produces H2O whenresponding with an acid, it besides dissolves in H2O quitereadily. When utilizing Na hydrated oxide to neutralize a lake,there may be several jobs. One job is that whenNa hydrated oxide dissolves in H2O, it gives off heat andthis may harm aquatic life beings. Besides this, vastsums of Na hydrated oxide is required to neutralize a lakehence big sums of this substance which is causticwill hold to be transported. This is a great hazard to theenvironment if a spill was to happen.The undermentioned equation shows that H2O is produced whenutilizing Na hydroxide.

2NaOH + H2SO4 & # 8211 ; * Na2 SO4 + 2H2OLimestone: Another manner to neutralize a lake is byliming. Birdliming of lakes must be done with considerablecautiousness and with an consciousness that the aquatic ecosystemwill non be restored to its original pre-acidic province eventhough the pH of H2O may hold returned to more normaldegrees. When limestone dissolves in H2O it produces Cdioxide.

This could be a job since a higher content ofC dioxide would intend a lowered O content particularlywhen much algae growing is present. As a consequence, fish andother beings may endure. Limestone besides does non fade outevery bit readily as Na hydrated oxide therefore taking a longer period ofclip to respond with sulphuric acid to neutralize the lake. Theequation for the neutralisation utilizing limestone is as follows:Ca CO3 + H2SO4 & # 8211 ; * CaSO4 + H2O.four ) The consequence of the Acid or inordinate Base on the works and carnal life:You will likely happen that there aren & # 8217 ; t many aquaticpopulating beings in Waterss that are overly basic oracidic.

A high acidic or basic content in lakes kill fishesand other aquatic species. Drawn-out exposure to acidic oroverly basic conditions can take to generative failureand morphological aberrance of fish. A lowered pH tends toneutralize toxic metals. The accretion of such metals infish contaminates nutrient ironss of which we are a portion as thesemetals can do fish unfit for human ingestion.Acidification of a lake causes a decrease of the productionof phytoplankton ( which is a primary manufacturer ) every bit good as inthe productiveness of the growing of many other aquatic workss.

In acidic conditions, zooplankton species will likelybecompletely eliminated. In add-on, bacterialdecomposition of dead affair is earnestly retarded inacidified lake Waterss. Other effects of acidic conditionsarean overfertilization of algae and other microscopic workslifecausing algae blooms. Giantism of these consumesrapidly most of the O in H2O therefore doing other lifesignifiers to decease from oxygen famishment.When there are inordinate base or acid in Waterss, nonmerely do aquatic beings get affected but animate beings who dependon aquatic workss to last will hunger excessively, since fewaquatic workss survive in such conditions. Therefore eachbeing in the aquatic ecosystem is effected by inordinatebasic or acidic conditions because anything impacting onebeing will impact the nutrient concatenation, directing reverberationsthroughout the full ecosystem.V ) The factors that govern this works & # 8217 ; s location, if thisworks employs 40 % of the towns people:The major factors that would regulate this works & # 8217 ; slocation would be whether there is ready entree to rawstuffs ; whether the location is near to majortransit paths ; whether energy resources are readilyavailable and if there is an equal H2O supply in thecountry. Since this works would use 40 % of the towns people,the works should be near to the town while still far plentyso that in instance of any escape of the works, the town will bewithin a safe distance of being badly affected.

Thefactor of whether the general life conditions in the countryare suited for the workers should besides be considered every bit good.
