Investigating the effect of concentration on the rate of reaction between marble chips and Hydrochloric acid Section 1: Planning Introduction In this experiment I will be investigating the reaction between different concentrations of acid and marble chips. I will be measuring the speed and rate of which gas is given off. I know that the gas given off will be carbon dioxide and that the reaction will be as follows: Calcium Carbonate + Hydrochloric Acid --> Calcium Chloride + Water + Carbon Dioxide Or CaCO3 + 2HCl --> CaCl2 + H2O + CO2 On the left are the reactants. These are the chemicals that I will start off with. On the right are the products. These are what will be produced at the end of the experiment. Reactants and products are very rarely the same, as they react with one another to form other things. There will always be the same number of atoms in the...
