Equivalent weight of in the reaction is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Oxidation states: $Fe(+2 \rightarrow +3)$, change = 1. $S(-1 \rightarrow +4)$, change = 5 per $S$, total $5 \times 2 = 10$. <br>$\text{Total n-factor} = 1 + 10 = 11$. $\text{Eq. wt} = M/11$.
