Chemical equations

Question

Consider the reaction when aqueous solutions of sodium carbonate and chromium(III) sulfate are combined. The net ionic equation for this reaction is:

Answer 1

The net ionic equation does NOT include spectator ions, so only the species involved in forming the precipitate are included.

2Cr³⁺(aq) + 3CO₃^2-(aq) ==> Cr₂(CO₃)₃(s) ... balanced net ionic equation
