Question

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

To determine the spectator ions, we need to identify the ions that are present on both sides of the arrow and do not participate in the reaction.

In this case, the balanced chemical equation is:

2KMnO4(aq) + 10FeSO4(aq) + 8H2SO4(aq) → K2SO4(aq) + 2MnSO4(aq) + 5Fe2(SO4)3(aq) + 8H2O(l)

The complete ionic equation is:

2K+(aq) + 2MnO4-(aq) + 10Fe2+(aq) + 10SO4 2-(aq) + 8H+(aq) + 8SO4 2-(aq) → 2K+(aq) + 2SO4 2-(aq) + 2Mn2+(aq) + 5Fe3+(aq) + 30SO4 2-(aq) + 8H2O(l)

The spectator ions are K+(aq), SO4 2-(aq), and Fe2+(aq) because they appear on both sides of the equation and are not involved in the reaction.

Therefore, the best choice is C, which includes only K+(aq), SO4 2-(aq), and Fe2+(aq).
