What is the n-factor of when it is oxidized to and ? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$Fe^{2+} \rightarrow Fe^{3+} + e^-$ ($1 e^-$). <br>$C_2O_4^{2-} \rightarrow 2CO_2 + 2e^-$ ($2 e^-$). <br>$\text{Total electrons lost} = 1 + 2 = 3$. <br>Thus, the n-factor is 3.
