Chemistry Coursework Rate of Reaction Plan I plan to find out how the concentration of water and hydrochloric acid (making acid rain) affects the erosion of marble buildings and statues in Greece. I am going to find out how the concentration affects the rate of reaction. The equipment I will use:> Hydrochloric Acid (HCL)> Water> A conical flask> A 50ml measuring cylinder> Calcium Carbonate> A clock> A digital weight balance> A gas syringe> Bungs The same equipment will be used throughout the experiment so it is a fair test. The equipment is a constant throughout the experiment. Firstly: I will prepare different concentrations of hydrochloric acid. These concentrations provide the only variable in the experiment. I will not prepare a solution containing only water because the solution would not contain any reactant particles for the water particles to react with, so no reaction would occur. The concentrations of the acid in the experiment will be: Water Cm3 HCl Cm3 Concentration HCl 40 30 25 20 10 0 10 20 25 30 40 50 0.25 0.7 1 1.5 4 50 Secondly:...
