Investigate the rate of reaction between Calcium Carbonate and Hydrochl

Investigate the rate of defendion amidst Calcium Carbonate and Hydrochloric Acid at different concentrationsAimTo Investigate the rate of reaction between Calcium Carbonate andHydrochloric Acid at different concentrations.Background KnowledgeI know from my knowledge of science, that by adding together a carbon copyate and an acid, that a salt, water and Carbon Dioxide are conjure upd. Therefore in order to measure the rate of reaction, one ofthese products needs to be measured, and the rate at which it isproduced can be used to define the rate of the reaction. The methodsthat can be used are either to measure the mass of the solution atintervals. Or to measure the produce of gas (Carbon Dioxide).PredictionUsing the known formulaACID + CARBONATE SALT + CARBON DIOXIDE + WATERI can predict the reaction of my examine to beHYDROCHLORIC + CALCIUM CALCIUM + WATER + CARBONACID CARBONATE CHLORIDE DIOXIDEThe Chemical Formula is listed below2HCl + CaCO3 CaCl2 + H20 + CO2I think that as th e thousand of the acid goes up, the amount of gasproduced will also go up.I have based this on my knowledge that calcium carbonate does notreact in water. Therefore in solutions with little acid and to a greater extentwater, the calcium carbonate will not react as much as it would inpure acid for example. To make each of the different strengths of theacid, water is added to a solution of 2M hydrochloric acid. Thereforein the 0.2 value, there will be a hatful of water, and so it is notexpected that much gas will be produced.My predicted graph shows what I expect. On the x-axis, as the molarityincreases, the gas produced on the y-axis does likewise. save therewill be a point reached where the maximum limit of gas has beenprod... ...a clear trend that as the molarity of theacid increases, the volume of carbon dioxide will also do the same.There is an even trend going up, with a straight line to fit as theline of best fit.The suit for this pattern is the same as that that was made in theprediction. As the concentration of the acid increases, there are moreHCl molecules and so there is more probability of the calcium carbonatemolecules colliding with these and so reacting to form calciumchloride. With the reaction occurring more often, the products willform in a greater quantity and so more carbon dioxide is produced.This reflects the rate of the reaction on the graph and proves myprediction and its theory correct.EvaluationAs the experiment was computer generated, it simulated how theexperiment would have been conducted. It accounted for charitable errors inall aspects of the expriment.
