NCERT Q7

Write the balanced chemical equations for the following reactions.

(d) Barium chloride + Potassium sulphate → Barium sulphate + Potassium chloride

 

Answer

(d) BaCl 2 + K 2 SO 4   →  BaSO 4 + KCl

To balance Chlorine and Potassium,

Multiply KCl by 2

BaCl 2 + K 2 SO 4   →  BaSO 4 + 2 KCl
