In that compounds `KMnO_(4) and K_(2)Cr_(2)O_(7)` the highest oxidation state the element:

State three uses of KMnO_(4) and K_(2)Cr_(2)O_(7) each.

If stoichiometric quantities of KMnO_(4) and K_(2)Cr_(2)O_(7) mixture is added for the oxidation of Fe^(2+) " to " Fe^(3+) in acidic medium, then Fe^(2+) will be oxidised

If equal volume of 1M KMnO_(4) and 1M K_(2)Cr_(2)O_(7) solution are used to react with Fe^(2+) oxidized will be :

What happens when (i) KMnO_(4) is heated ? (ii) K_(2)Cr_(2)O_(7) is heated ?

In the conversion of K_(2)Cr_(2)O_(7) to K_(2)CrO_(4) the oxidation number of the following changes
