Have a little read: ... The Erosion of Marble Background Information Marble ( calcium carbonate ) reacts with acid to give off carbon dioxide, water and a salt (calcium chloride). The carbonate 'fizzes' and dissolves when acid is added. Some pollutants in air are acidic gases, namely sulphur dioxide and nitrogen dioxide. These gases react with other gases, and then rain water which makes the rain water acidic. Acid rain can form as follows; Sulphur dioxide + oxygen = sulphur trioxide 2SO2 + O2 = 2SO3 then, sulphur trioxide + water = sulphuric acid SO3 + H2O = H2SO4 Reactions like this makes rain water become acidic. Acid rain has a pH of between 5 and 2. Thus acid rain can attack marble and limestone as well as water biology and may be responsible for the death of trees in Europe. Title - Investigate how changing the concentration of hydrochloric (HCl) alters the rate of its reaction with marble. calcium + hydrochloric
