Jason Goodwill Chemistry Coursework Investigation: The Effect Of Acid Rain On Building Materials Due to dissolved carbon dioxide rainwater is naturally acidic in the form of the weak carbonic acid. However gases such as sulphur dioxide and nitrogen oxides cause acid rain, which is responsible for the corrosion of buildings and damage to the wildlife. The burning of fossil fuels releases these gases into the atmosphere when the small quantities of sulphur react with the oxygen in the air, forming sulphur dioxide. The aim of this investigation is to investigate the way in which one factor alters the rate of erosion of building materials such as stonework and metals. To conduct this experiment I can use marble chips (calcium carbonate) or magnesium ribbon and in place of sulphuric acid dilute hydrochloric acid will be used. This is because sulphuric acid produces an insoluble salt which prevents any further reaction with the...
