Question Question 2(2020)
Distinguish between the following pairs of compounds using a reagent as a chemical test.
Ammonium sulphate crystals and sodium sulphate crystals
Ammonium salts react with alkalis on heating to liberate Ammonia gas. Hence, we can use NaOH as reagent to distinguish between Ammonium Sulphate crystals and Sodium Sulphate crystals. Below is the reaction for the same:
(NH4)2SO4 + 2NaOH ⟶ Na2SO4 + 2H2O + 2NH3 [g]
