An investigation into how surface area affects the rate of reaction Aim: To investigate the factors which affect the rate of reaction between marble chips and hydrochloric acid, with one in specific detail. Scientific knowledge: Marble chips erode when they are exposed to acid rain or pollution. Erosion is evident when you look at older marble buildings as in certain cases the erosion take a long time. It is more likely to occur in areas, where there is more pollution. This is because there are a greater number of industries in city than in the countryside. Especially the higher amount of cars which release carbon dioxide, formed as a waste gas in reactions such as internal combustion. Carbonic acid (the product of carbon dioxide and water) mixes with acidic pollutants such as sulphur dioxide and oxides of nitrogen to form acid rain. When this rain contacts the rocks, a chemical reaction takes...
