Question
In the reaction $As_2S_3 + HNO_3 \rightarrow H_3AsO_4 + H_2SO_4 + NO_2 + H_2O$, the $n$-factor of $As_2S_3$ is:
Answer: C
💡 Solution & Explanation
$As_2^{+3} \rightarrow 2As^{+5}$ (loss of 4 $e^-$). <br>$S_3^{-2} \rightarrow 3S^{+6}$ (loss of $3 \times 8 = 24$ $e^-$). <br>Total electrons lost per molecule = $4 + 24 = 28$.
