Question

28. Aqueous solutions of sodium su
Identify the type of chemical
uons of sodium sulphate is mixed with adequate solution of barium chloride.
Type of chemical change and write the balanced chemical equation.​

Answer 1

We write the equation for the formation of

BaSO4(s) as:BaCl2(aq)+Na2SO4(aq)→BaSO4(s)⏐↓+2Naq)

Alternatively, we could write the net ionic equation:Ba2++SO2−4→BaSO4(s)⏐⏐↓

In other words, the Na+ , and Cl−

ions are along for the ride. The are passengers, spectators, and play no part in the macroscopic reaction.

Answer 2

Answer:

cuso4+bacl2------/baso4+cucl2
