To perform the reaction between sodium sulphate and barium chloride solutions and classify it on:
i. Combination reaction
ii. Decomposition reaction
iii. Displacement reaction
iv. Double displacement reaction
Theory
Reaction: BaCl2(aq) + Na2SO4(s) → BaSO4(s) + NaCl(aq)
Chemicals Required
Apparatus Required
Procedure
Observation
When the solutions of sodium sulphate and barium chloride are mixed a white precipitate is formed which is insoluble in HCl.Inference
1. When sodium sulphate chemically reacts with barium chloride in the form of their aqueous solutions, white precipitate of barium sulphate appears. This confirms the presence of sulphate (SO4)2- ions.
Reaction: BaCl2(aq) + Na2SO4(s) → BaSO4(s) + NaCl(aq)
Precautions
1. Handle the acids and alkali carefully. 2. Use equal volumes of barium chloride and sodium silphate solutions. 3. Clean the apparatus thoroughly before using it.Go to List of Experiments
Text Solution
Solution : `BaCl_(2)(aq) + Na_(2)SO_(4) (aq) rarr BaSO_(4)(s) + 2NaCl(aq.)` <br> When a solution of sodium sulphate is added to a solution of barium chloride, then a white precipitate of barium sulphate is formed along with sodium chloride solution. Hence, this reaction is precipitation reaction.

When barium chloride combines with sodium sulphate in the form of their aqueous solutions, a white precipitate of barium sulphate is formed which is insoluble in water. The reaction also creates sodium chloride, which remains dissolved in water and so cannot be seen. Here, the products formed are entirely different from the reactants in chemical composition and chemical properties. So this reaction is a chemical change.
This video explains the chemical change occurs during the reaction between sodium sulphate and barium chloride.
