(b) When ammonium chloride is heated, it undergoes …………… [thermal decomposition/dissociation].
(c) Heating ammonium chloride with sodium hydroxide produces …………… [ammonia, nitrogen].
Answer
(a) Ammonium chloride is a soluble salt prepared by neutralization.
NH3 (gas) + HCl (gas) ⟶ NH4Cl (solid)
(b) When ammonium chloride is heated, it undergoes thermal dissociation.
NH4Cl ⇌ NH3 + HCl
(c) Heating ammonium chloride with sodium hydroxide produces ammonia.
NH4Cl + NaOH ⟶ NaCl+ H2O + NH3
