Question

Write the net ionic equation for this precipitation reaction. Include physical states.

(NH₄)₂CO₃(aq)+Ca(ClO₄)₂(aq)⟶CaCO₃(s)+2NH₄ClO₄(aq)

net ionic equation:

Answer 1

we have below given equation

(NH4)2CO3 (aq) + Ca(ClO4)2 (aq) --> CaCO3 (s) + 2 NH4ClO4 (aq)

Total ionic equation is

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

2 NH4+ (aq) + CO32- (aq) + Ca2+ (aq) + 2 ClO4- (aq) --> CaCO3 (s) + 2 NH4+ (aq) + 2 ClO4- (aq)

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

After removing Spectator ions, net ionic equation is:

Ca2+ (aq) + CO32- (aq) --> CaCO3 (s)

Answer:

Ca²⁺ (aq) + CO₃^2- (aq) --> CaCO₃ (s)
