321331 \(\mathrm{\mathrm{KMnO}_{4}}\) can be prepared from \(\mathrm{\mathrm{K}_{2} \mathrm{MnO}_{4}}\) as per the reaction:
\(\mathrm{3 \mathrm{MnO}_{4}^{2-}+2 \mathrm{H}_{2} \mathrm{O} \rightleftharpoons 2 \mathrm{MnO}_{4}^{-}+\mathrm{MnO}_{2}+4 \mathrm{OH}^{-}}\).
The reaction can go to completion by removing \(\mathrm{\mathrm{OH}^{-}}\)ions by adding.

321332 When \(\mathrm{\mathrm{KMnO}_{4}}\) solution is added to oxalic acid solution, the decolourisation is slow in the beginning but becomes instantaneous after some time because

321333 Number of electrons transferred in each case when \(\mathrm{KMnO}_{4}\) acts as an oxidizing agent to give\(\mathrm{MnO}_{2}, \mathrm{Mn}^{2+}, \mathrm{Mn}(\mathrm{OH})_{3}, \mathrm{MnO}_{4}^{2-}\) are, respectively.

321334 Identify the correct statements from below.
(I) The chromate ion is square planar.
