Calcium phosphide

Calcium phosphide is a chemical compound made of calcium and phosphide ions. The chemical formula is Ca₃P₂. The molar mass is around 182.18 g/mol. It appears as a red-brown solid. It is used as rodenticide, fumigant, and preparation of fireworks and flares due to phosphine gas.

Production

It can be made when calcium metal reacts with phosphorus to make calcium phosphide.

The balanced chemical equation is:

6Ca + P₄ → 2Ca₃P₂

Reactions with calcium phosphide

When calcium phosphide reacts with water, it makes calcium hydroxide and phosphine gas.

The balanced chemical equation is:

Ca₃P₂ + 6H₂O → 3Ca(OH)₂ + 2PH₃
