-factor of as an oxidizing agent when it is reduced to is: — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Step 1:** $Fe_2(SO_4)_3 \rightarrow 2FeSO_4$. <br>**Step 2:** $Fe$ goes from +3 to +2. Change per atom = 1. <br>**Step 3:** Since there are 2 $Fe$ atoms per molecule, the total electrons gained ($n$-factor) = 2.
