Question

1. Which is the white precipitate obtained when a few drops of Barium chloride solution is added to dilute sodium sulphate solution? Write the general formula​

Answer 1

Barium sulphate

Explanation:

• When a few drops of Barium chloride solution is added to dilute sodium sulphate solution white precipitate of barium sulphate is formed.
• BaCl₂ + Na₂SO₄ → BaSO₄ + 2NaCl
• It is a double displacement reaction.

Answer 2

Answer: Barium Sulphate as white precipitate

Explanation:

The general equation for the reaction is -

Ba²⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + SO₄²⁻(aq) ⇒ BaSO₄(aq) + 2NaCl(aq)

and the general formula for white precipitate Barium Sulphate is BaSO₄
