Class 11 NEET Chemistry Redox Reactions Questions

Question : 15 of 30

Marks: +1, -0

\mathrm{MnO}_4^{-}+\mathrm{C}_2 \mathrm{O}_4^{2-}+\mathrm{H}^{+}\rightarrow \mathrm{Mn}^{2+}+\mathrm{CO}_2+\mathrm{H}_2 \mathrm{O}

Solution: 👈: Video Solution

n-factor of

\mathrm{MnO}_4^{-} \Rightarrow 5

n-factor of

\mathrm{C}_2\mathrm{O}_4^{2-} \Rightarrow 2

Ratio of n-factors of

\mathrm{MnO}_4^{-}

and

\mathrm{C}_2\mathrm{O}_4^{2-}

5:2

So, molar ratio in balanced reaction is

2:5

∴ The balanced equation is

2\mathrm{MnO}_4^{-}+5\mathrm{C}_2\mathrm{O}_4^{2-}+16\mathrm{H}^{+} \rightarrow 2\mathrm{Mn}^{2+}+10\mathrm{CO}_2+8\mathrm{H}_2\mathrm{O}
