When Ammonium chloride reacts with calcium hydroxide [Base], it produces Ammonia [Gaseous state].
The balanced chemical equation for the reaction will be :
2(NH4Cl) + Ca(OH)2 = (CaCl)2 + 2(NH3) (g) + 2(H2O).
Hope this helps!

... NH3 i.e, ammonia has high affinity towards water and is soluble in water. Calcium hydroxide gets converted to calcium oxide which absorbs moisture and helps in extracting ammonia in its dried form.
