Question

Name the gas liberated when calcium carbide react with water

Answer 1

 Calcium carbide reacts with water to produce acetylene gas, C2H2. CaC2 (s) + 2 H2O (l) ----> C... Calcium carbide reacts with water to produceacetylene gas, C2H2.

Answer 2

Answer:

Acetylene gas (C₂H₂) is produced by the reaction of calcium carbide on water.

Explanation:

• One unit Calcium carbide (CaC₂) when reacts with two molecules of  water (H₂O) gives calcium hydroxide (Ca (OH)₂ and acetylene (C₂H₂).

• CaC₂ + 2H₂O → Ca (OH)₂ + C₂H₂

• Acetylene (C₂H₂) is used for welding and cutting.

• It is a colorless gas.

• IUPAC name of acetylene is ethyne.

• This method is the industrial method preparation of alkyne.
