When pyrolusite is roasted in a basic medium KOH with air, a green col – InterviewSolution

1.	When pyrolusite is roasted in a basic medium KOH with air, a green coloured compound P is formed. Cl2 can convert P to a compound Q whose aqueous solution is purple in colour. If the oxidation state of Mn in P is X and the number of unpaired electrons in P is Y and that in Q is Z. Then find the value of XX−Y−Z
Answer» When pyrolusite is roasted in a basic medium $K O H$ with air, a green coloured compound $P$ is formed. $C l_{2}$ can convert $P$ to a compound $Q$ whose aqueous solution is purple in colour. If the oxidation state of $M n$ in $P$ is $X$ and the number of unpaired electrons in $P$ is $Y$ and that in $Q$ is $Z$ . Then find the value of $\frac{X}{X - Y - Z}$
