Answer

Explanation:

Step1: Define spectator ions

Spectator ions are ions that appear on both sides of a total - ionic equation and do not participate in the actual chemical reaction.

Step2: Analyze the given equation

In the equation (2H^{+}+CrO_{4}^{2 -}+Ba^{2 +}+2OH^{-}\longrightarrow Ba^{2 +}+CrO_{4}^{2 -}+2H_{2}O), we observe the ions on both sides. The (Ba^{2+}) ion is present on the left - hand side and the right - hand side of the equation, and the (CrO_{4}^{2 -}) ion is also present on both sides.

Answer:

D. (CrO_{4}^{2 -}) and (Ba^{2 +})
