23. Ans :-
Balanced chemical equation is :
K2CO3 (aq) + H2SO4 (aq) --------------------> K2SO4 (aq) + H2O (l) + CO2 (g)
# Strong electrolytes are completely dissociated in aqueous solution. In this reaction strong electrolytes are: K2CO3 , H2SO4 and K2SO4
# Weak electrolytes are partially dissociated in aqueous solution. In this reaction weak electrolytes are: H2O (l) and CO2 (g)
Therefore,
Complete balanced ionic equation is :
2 K+ (aq) + CO32- (aq) + 2 H+ (aq) + SO42- (aq) --------------------> 2 K+ (aq) + SO42- (aq) + H2O (l) + CO2 (g) |
Here, K+ and SO42- are spectators ions that is those ions which appear both side of complete ionic equation and cancel out when we write net ionic equation.
So,
Net ionic equation is :
CO32- (aq) + 2 H+ (aq) --------------------> H2O (l) + CO2 (g) |
