Discussion. Acetylene (ethyne) gas is commonly generated by reacting calcium carbide with water. The equation is CaC 2 (s ) + 2 H 2 O(l ) --> Ca(OH) 2 (aq ) + C 2 H 2 (g ) . Acetylene gas and chlorine react upon contact at room temperature, so when acetylene is generated in a chlorine atmosphere it immediately inflames.
Procedure for the preparation of acetylene. Lumps of calcium carbide are placed on the layer of sand in a conical flask fitted with a dropping funnel and delivery tube. The free end of the delivery tube is inserted into a wash bottle containing acidified copper sulphate solution, and the wash bottle's exit end is fitted into the beehive shelf ...
