Question
The $n$-factor of $As_2S_3$ in the reaction $As_2S_3 \rightarrow AsO_4^{3-} + SO_4^{2-}$ is:
Answer: 28
💡 Solution & Explanation
**1.** $2As^{3+} \rightarrow 2As^{5+}$ involves loss of $2 \times 2 = 4 e^-$. <br>**2.** $3S^{2-} \rightarrow 3S^{6+}$ involves loss of $3 \times 8 = 24 e^-$. <br>**Total $n$-factor** = $4 + 24 = 28$.
