Question
How is ammonia gas prepared in laboratory starting from NH4Cl? State the conditions and balanced equation for the preparation.
Solution
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 :
`\[\ce{2NNH4CI + Ca(OH)2 ->[\Delta] CaCI2 + 2H2O + 2NH3}\]`
