Question

Write the net ionic equation for the reaction which takes place when BaCl2(aq) is added to K2SO4(aq).

Answer 1

we have below given equation

BaCl2 (aq) + K2SO4 (aq) --> BaSO4 (s) + 2 KCl (aq)

Total ionic equation is

Spectator ions should not be removed here. Spectator ions are part of total ionic equation

Ba2+ (aq) + 2 Cl- (aq) + 2 K+ (aq) + SO42- (aq) --> BaSO4 (s) + 2 K+ (aq) + 2 Cl- (aq)

Spectator ions should be removed now. Spectator ions are not part of total ionic equation

After removing Spectator ions, net ionic equation is:

Ba2+ (aq) + SO42- (aq) --> BaSO4 (s)

Ba²⁺ (aq) + SO₄^2- (aq) --> BaSO₄ (s)
