... Chemistry Investigation: Does the concentration of hydrochloric acid affect its rate of reaction with calcium carbonate? Aim As stated in the title, I will investigate the differences in the rates of reaction between hydrochloric acid and calcium carbonate if the concentration of the acid is varied. This is the equation for this reaction: 2HCl + CaCO3 CaCl2 + H2O + CO2 Hydrochloric acid + Calcium Carbonate Calcium chloride + Water + Carbon Dioxide Possible Variables that could be used The variables that may have an affect on this experiment are: * Size of marble chip - the size of the marble chip will affect our experiment, because this dictates the surface area. The larger the surface area, the more acid that will be in contact with the hydrochloric acid and able to react. * Concentration of hydrochloric acid - this is the proportion of hydrochloric acid in the solution. * Volume of acid - this will
