The clay mineral kaolinite (Al,Si,O;(OH)4) is formed by the weathering action of water containing dissolved carbon dioxide on the feldspar mineral anorthite (CaAl,Si,Og). Write a balanced chemical equation for the reaction that occurs. The CO, forms H,CO3 as it dissolves. As the pH is lowered, will the weathering occur to a greater or a lesser extent?
