Our Aim: To investigate the effect of acid concentration on the rate of the following chemical. Calcium Hydrochloric Calcium water Carbon Carbonate acid Chloride Dioxide CoCa3 (s) 2HCl (aq) CaCl2 (aq) H2O (l) Co2 (g) Prediction: The time taken for a reaction to take place is known as the rate of reaction and there are many things that can change the rate of reaction. They are: - The concentration of Hydrochloric acid. - The temperature at which the reaction takes place, - Using a catalyst. - The surface area of Calcium Carbonate. - What is done to the conical flask during the experiment (shaking). - Fair testing. Changing the concentration, will change the rate of reaction, this is because the higher the concentration the more particles of hydrochloric acid there are to collide and react with Calcium Carbonate. More collisions mean a faster reaction. HCl 0.5M least concentrated. HCl 1.5M HCl 2.5M most concentrated. Changing the temperature would also change the...
