Rates of Reaction Coursework

Planning

Aim of experiment: The aim of this experiment is to investigate the rate of reaction of an acid with a rock. There are different factors that effect the rate of reaction between calcium carbonate (marble chips) and hydrochloric acid. The factor that concerns my investigation is the concentration of the liquid reactant, which in this case is the hydrochloric acid. The aim is to experiment and to observe how the concentration of the acid effects the rate of reaction between the limestone and the acid. Since limestone is a carbonate, a good sample of it would be marble known as calcium carbonate.

There were many different type of acid’s available including nitric acid, hydrochloric acid and sulphuric acid. Hydrochloric acid was chosen to use in the experiment, as it would give us accurate results as it contained the properties of acid rain. Calcium Carbonate (marble chips or limestone) would be used as a rock. Calcium Carbonate (Marble) is a metamorphic rock.
