The carbide lamp operates because of a chemical reaction between calcium carbide, and water: CaC 2 + H 2 O =>C 2 H 2 + CaO + heat However, there is another chemical reaction that occurs within the lamp bottom between the lime (calcium oxide) and the water to produce calcium hydroxide CaO + H 2 O =>Ca(OH) 2 The water is stored in a reservoir .
