Question

Write a balanced chemical equation of Water is added to Calcium carbide

Answer 1

Balanced chemical equation of Water is added to Calcium carbide

• Calcium carbide $\left({\mathrm{CaC}}_2\right)$ reacts with water to give Ethyne $\left({\mathrm{C}}_2{\mathrm{H}}_2\right)$ or Acetylene gas and Calcium hydroxide $\mathrm{Ca}{\left(\mathrm{OH}\right)}_2$ as the products.
• This method is used to prepare Acetylene from Calcium carbide.
• Acetylene is basically a colorless gas.
• The chemical reaction is as follows:

$\underset{\mathrm{Calcium}\mathrm{carbide}}{{\mathrm{CaC}}_2\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\to \underset{\mathrm{Calcium}\mathrm{hydroxide}}{\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\left(\mathrm{l}\right)}+\underset{\mathrm{Acetylene}}{{\mathrm{C}}_2{\mathrm{H}}_2\left(\mathrm{g}\right)}$
