Use a capillary tube to connect this flask to a measuring cylinder upside down in a bucket of water downwards displacement. 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. To do this i will change the concentration of the hcl and measure how that affects the amount of co2 produced during the reaction and hence find the rate.
