Q. How many moles of $KMn{O}_4$ are required to oxidise one mole of $SnC{l}_2$ in acidic medium ?

Q. Find the number of moles of $KMn{O}_4$ needed to oxidise one mole $C{u}_{2}S$ in acidic medium. The reaction is $KMn{O}_4+C{u}_{2}S\to M{n}^{2+}+C{u}^{2+}+S{O}_2$

Q. Find the number of moles of $KMn{O}_4$ needed to oxidise one mole $C{u}_{2}S$ in acidic medium. The reaction is $KMn{O}_4+C{u}_{2}S\to M{n}^{2+}+C{u}^{2+}+S{O}_2$

Q. For decolourisation of $1.5$ moles of ${KMnO}_4$ in acidic medium the moles of $H_2{O}_2$ requires$:$

Q. Assertion :The volume of 0.1M ${KMnO}_4$ required to oxidise 20 ml of 0.1 M oxalic acid in acidic medium is 20 ml. Reason: 2 moles of ${KMnO}_4$ = 5 moles of oxalic acid in acidic medium reaction.
