-factor of when it is reduced to is: — Redox Reactions and Volumetric Analysis Chemistry Question
Question
$n$-factor of $Fe_2O_3$ when it is reduced to $FeO$ is:
Answer: A
💡 Solution & Explanation
In $Fe_2O_3$, $Fe$ is +3. In $FeO$, $Fe$ is +2. <br>Change per $Fe$ atom = 1. <br>Since there are 2 $Fe$ atoms in $Fe_2O_3$, the total electrons gained ($n$-factor) = 2. [1]
