1 Calcium oxide, calcium hydroxide and calcium carbonate can be used to neutralise soil acidity. 2  Calcium carbonate can be used to remove acidic gases from coal-fired power station chimneys reducing harmful emissions and acid rain. We know this because the surroundings get warm. ] 2  reaction takes place. 3  This forms calcium hydroxide. 4  Calcium hydroxide is soluble in water and forms a solution known as limewater which is used to test for carbon dioxide. 5  Calcium oxide, calcium hydroxide and calcium carbonate can be used to neutralise soil acidity.
If the bedrock is a carbonate rock (such as limestone or dolomite) then groundwater containing weak acids will slowly dissolve the rock, creating caverns and sinkholes. Groundwater Erosion. Groundwater is somewhat acidic and this acid dissolves calcium carbonate (widely found in rocks all over the world) in rocks like limestone, (CaCO3). The water then filters through the cracks and joints in the rock, carrying the mineral out of the rock.
