Question

Write the chemical reaction for the Calcium carbide and water

Answer 1

The reaction between Calcium carbide and water:

1. Calcium carbide $\left({\mathrm{CaC}}_2\right)$ reacts with Water $\left({\mathrm{H}}_2\mathrm{O}\right)$ to produce colorless gas with an Ether-like odor known as Acetylene gas $({\mathrm{C}}_2{\mathrm{H}}_2)$.
2. The given reaction is an exothermic process.
3. Equation of preparation of Acetylene is as follows.

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