Aim To investigate the effect of varying the concentration of hydrochloric acid with the rate at which it reacts with calcium carbonate (limestone). Hypothesis The more concentrated the solution of the hydrochloric acid the faster the rate of reaction. Also the more dilute the concentration of hydrochloric acid the slower the rate of reaction. We can also predict that by doubling the concentration we can double the rate of reaction. e.g. 40 Rate of Reaction 20 Increasing Double 0 20 40 Volume of concentration % (not accurate) The above graph shows that is my hypothesis is correct what the graph showing the results will look like. The graph clearly shows that if the volume of concentration increases (or doubles) the rate of reaction will also increase (or double). Background knowledge The higher the concentration the faster the reaction is. In order for the limestone and hydrochloric to react: * They must collide with...
