Potassium permanganate works as oxidising agent both in acidic and basic medium. In both state, product obtained by ${\text{KMnO}}_{\text{4}}$ is respectively ______.

The gas responsible for underwater corrosion of iron and the product of corrosion, respectively, are -

Oxalic acid when treated with potassium permanganate in the presence of an acid, produces:

The number of moles of ${\mathrm{Br}}_2$ produced when two moles of potassium permanganate are treated with excess potassium bromide in aqueous acid medium is:

${\mathrm{MnO}}_2$ when fused with $\mathrm{KOH}$ and oxidized in air gives a dark green compound $\mathrm{X}$. In acidic solution, $\mathrm{X}$ undergoes disproportion to give an intense purple compound $\mathrm{Y}$ and ${\mathrm{MnO}}_2$. The compounds $\mathrm{X}$ and $\mathrm{Y}$. respectively, are
