Calcium carbide - Wikipedia

The reaction of calcium carbide with water, producing acetylene and calcium hydroxide, was discovered by Friedrich Wöhler in 1862. CaC 2( s ) + 2H 2 O ( aq ) → C 2 H 2 ( g ) + Ca(OH) 2 (aq ) This reaction was the basis of the industrial manufacture of acetylene , and is the major industrial use of calcium carbide.
