Question

What happens when aqueous solutions of Sodium sulphate and Barium chloride are mixed? Give a balanced equation for the reaction with state symbols. Name and define the type of chemical reaction involved in the above change.

Answer 1

When an Aqueous solution of the sodium sulphate is mixed with the Barium Chloride solution, then they will form precipitate of the Barium sulphate and Sodium Chloride.

Reaction will be,

BaCl₂ + Na₂SO₄ ---------- 2NaCl + BaSO₄

BaCl₂ = Barium Chloride

Na₂SO₄ = Sodium Sulphate

NaCl = Sodium Chloride

BaSO₄  = Barium Sulphate

__________________________________

This Reaction is the Double displacement reaction.

It may be defined as the Reaction in which the radicals are exchanged. For example, Cl of Barium chloride and SO₄²⁻ of Sodium sulphate is exchanged to form a new products.

Hope it helps.

Answer 2

Double displacement reaction takes place with the formation of sodium chloride and barium sulphate.

Na2SO4+BaCl2_____ NaCl2+BaSo4
