Chemistry

In the titration of $\mathrm{KMnO}_{4}$ and oxalic acid in acidic medium, the change in oxidation number of carbon at the end point is ___________.

Correct Answer:

16 \mathrm{H}^{+}+2 \mathrm{MnO}_{4}^{-}+5 \mathrm{C}_{2} \mathrm{O}_{4}^{2-} \rightarrow 10 \mathrm{CO}_{2}+2 \mathrm{Mn}^{2+}+8 \mathrm{H}_{2} \mathrm{O}

During titration of oxalic acid by

\mathrm{KMnO}_{4}

, oxalic acid converts into

\mathrm{CO}_{2}

\therefore

Change in oxidation state of carbon

=1
