Question

How is ammonia gas prepared in laboratory starting from NH₄Cl? State the conditions and balanced equation for the preparation.

Answer 1

Ammonium chloride is heated with calcium hydroxide (an alkali ), in ratio of 2: 3 by weight, to produce ammonia .

Reactants should be dry and in grounded state. The reactants are heated to get the products.

Balanced reaction :

`\[\ce{2NNH4CI + Ca(OH)2 ->[\Delta] CaCI2 + 2H2O + 2NH3}\]`
