    The spectator ions are K⁺ and NO₃⁻ ions.

    Explanation :

    The equation is K₂CrO₄(aq) + Ba(NO₃)₂(aq) → 2KNO₃(aq) + BaCrO₄(s)

    On the reactant side, there are 2K⁺, CrO₄²⁻, Ba²⁺ and 2NO₃⁻ ions.

    On the product side, there are 2K⁺ , 2NO₃⁻ ions and BaCrO₄ precipitate.

    Hence, K⁺ and NO₃⁻ do not react, and thus they are spectator ions.
