Investigating the rate of reaction between Marble Chips (Calcium Carbonate) and hydrochloric acid. ...
In the investigation I am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small/large pieces of Marble Chips (Calcium Carbonate) and Hydrochloric acid per minute. ...
The rate of reaction increases when the surface area of a solid reactant is increased. This happens because by increasing the surface area we are also increasing the rate of collisions between the particles. When there is more of the reactant to react with the reaction speeds up. Therefore, my hypothesis is: the reaction will be faster when using small chips, so the gas will be produced faster (the same amount of gas will be produced in all experiments). ... Measure 50cm of hydrochloric acid (using measuring cylinder). ... Add the marble chip and hydrochloric acid to the conical flask at the same time and close the top with cotton wool to prevent the spitting out of the reactants. ... Record the weight loss (gas given off) every 20 seconds for the 10 minutes of the reaction.
