Final answer:
The net ionic equation for the reaction between barium hydroxide and potassium acetate is Ba^2+(aq) + 2OH^-(aq) + 2K^+(aq) + 2C^-(aq) -> Ba(C2H3O2)2(s) + 2K^+(aq) + 2OH^-(aq).
Step-by-step explanation:
The net ionic equation for the reaction when aqueous solutions of barium hydroxide and potassium acetate are combined is:
Ba2+(aq) + 2OH-(aq) + 2K+(aq) + 2C-(aq) → Ba(C2H3O2)2(s) + 2K+(aq) + 2OH-(aq)
This equation represents the reaction between barium hydroxide (Ba(OH)2) and potassium acetate (CH3COOK). When these compounds are mixed, they react to form solid barium acetate (Ba(C2H3O2)2) and a solution containing potassium ions (K+) and hydroxide ions (OH-).
