Answer:

Upper C r upper O subscript 4 superscript 2 minus and Upper B a superscript 2 plus

Explanation:

The spectator ions are the ions that appear on each side of the reaction arrow.

2H⁺ + CrO₄²⁻ + Ba²⁺ + 2OH⁻ ⟶ Ba²⁺ + CrO₄²⁻ + 2H₂O

In this reaction, they are CrO₄²⁻ and Ba²⁺.

Answer:

CrO₄²⁻ and Ba²⁺
