In the reaction , the -factor of is: — Redox Reactions and Volumetric Analysis Chemistry Question

💡 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 = $4 + 24 = 28$.
