Rate of Reaction between Calcium Carbonate and Hydrochloric acid The Problem To investigate how changing the concentration of acid effects the rate of reaction between calcium carbonate and hydrochloric acid. Background Knowledge Symbol equation CaCO3 + 2 HCl --> CaCl2 + CO2 + H2O Observations * Fizzing and bubbling. * The white solid disappears to give a colourless solution * Container heats up Rate of reaction Rate of reaction is the speed at which a reaction occurs, it can be found by recording the amount of reactants used up or the amount of product formed in a given time. For example in the reaction between hydrochloric acid and sodium thiosulphate a fine yellow precipitate of sulphur is produced. The rate of reaction can be measured as follows. 1. A cross is marked on a piece of paper. 2. A beaker with a volume of sodium thiosulpate is placed on the cross. 3. Dilute hydrochloric acid is added and a stopwatch is started and the time...
