Identify all the spectator ions in the following reaction. 2KMnO₄(aq) + 10FeSO₄(aq) + 8H₂SO₄(aq) → K₂SO₄(aq) + 2MnSO₄(aq) + 5Fe₂(SO₄)₃(aq) +8H₂O(l)

Question

Quizplus · Accepted Answer

Spectator ions are ions that do not participate in the chemical reaction and remain unchanged throughout the reaction. In this reaction, the ions K⁺ and SO₄^2- do not change and remain the same on both sides of the equation, hence they are spectator ions. Fe²⁺ participates in the reaction and is not a spectator ion. Mn²⁺ is a product formed after the reaction and hence it is not a spectator ion.
