    Calcium carbide also is used to make calcium cyanamide, CaCN 2, a fertilizer component and starting material for certain plastic resins. Calcium hydroxide, also called slaked lime, Ca(OH) 2, is obtained by the action of water on calcium oxide. When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the ...
