Investigate how the concentration of hydrochloric acid effects the rate at which it reacts with calcium carbonate :: GCSE Chemistry Coursework Investigation

Investigate how the concentration of hydrochloric point effectuate the prescribe at which it reacts with calcium carbonateInvestigation be afterAim===Investigate how increasing the concentration of the solutionhydrochloric acid effects and alters the aim at which it reacts withmarble chip, calcium carbonate.Rate of response is touch by six main factors* Temperature* Surface atomic number 18a of a warm* Concentration of a solution* Pressure of a gas* By using catalysts* Using biological catalysts called EnzymesAs outlined above the rate of a reaction increases when temperatureincreases, the concentration of dissolved reactants increases, thepressure of gases increases, solid reactants are in smaller pieces andof greater surface area and also if a catalyst is used.For this taste I have been asked to pay particular care tothe factor CONCENTRATION, and the ways in which it affects the rate atwhich a reaction takes place.We can stones throw the rate of reaction by beat the maga zine at which theproducts of the reaction are produced or the reactants used up and in that respect are a few different ways of doing this such asBy measuring gas volumeHere the marble chips and ignore hydrochloric acid are put in aconical flask. This is attached to a gas syringe, which collects andmeasures the volume of gas formed. At regular clipping intervals ameasurement is then taken of the volume of gas collected.another(prenominal) way to measure the volume of gas produced is to displace waterfrom a measuring cylinder as per diagram below.We can also measure the rate of reaction by measuring mass loss presentwhen a gas is lost the mass decreases, which can be calculated byplacing the flask on a balance.The last way is to melodic line how long it takes for a precipitate to formsuch as in the chemical reaction the thiosulphate reaction.I conducted a preliminary experiment and from this determined that themost reliable and accurate way to measure the dismission of carbond ioxide gas would be by using a measuring cylinder to see thedisplacement of water and therefore determining how a lot carbondioxide has been produced.HypothesisI predict that as time increases so pass on the amount of carbon dioxideproduced however throughout the experiment the rate of reaction willslow because as time increases there will be less and less un-reacted hints present to take part in fruitful collisions and result incarbon dioxide water and calcium chloride be formed, this meansthat the time between fruitful collisions will increase because aparticle will take longer to find another un-reacted particle withenough activation energy to collide and react with.I ruminate that as the concentration of the hydrochloric acid
