Solution

Hi Rishav,

When a small piece of sodium metal is put into a trough containing water, then it reacts with water to produce calcium hydroxide along with the evolution of hydrogen gas. The following reaction takes place.

Ca + 2H₂O→ Ca(OH)₂ + H₂

Hope, this answers your question.

Best wishes!
