Write NIE: Review

Question

Does a reaction occur when aqueous solutions of potassium carbonate and calcium acetate are combined?

yes/no

If a reaction does occur, write the net ionic equation.Be sure to specify states such as (aq) or (s).

If a box is not needed leave it blank.

+

Answer 1

K₂CO₃ (aq) + Ca(OOCCH₃)₂ (aq) ==> 2KOOCCH₃ (aq) + CaCO₃ (s) ... balanced molecular equation

To obtain the NIE, you need only consider the ions making up the precipitate (CaCO₃). Others are spectators.

Ca²⁺(aq) + CO₃^2-(aq) ==> CaCO₃(s) ... NIE (net ionic equation)

Answer 2

Yes

K₂CO₃ (aq)+Ca(OOCCH₃)₂ (aq)=2KOOCCH₃ (aq)+CaCO₃ (s)
