Copper sulphate can be produced by reacting copper carbonate with sulphuric acid. Water and carbon dioxide are also produced. Which of these compounds is a salt?
Limescale is a hard deposit that can block pipes. Limescale is mainly formed from calcium carbonate, which is a base. Limescale remover contains an acid, often hydrochloric acid, which reacts with the limescale to form calcium chloride. Water and carbon dioxide are also produced.
