When $H_2S$ is passed through $Hg_2^{2+}$ solution,the products obtained are:

The species given below that does $NOT$ show disproportionation reaction is :

White $P_4$ reacts with caustic soda,the products are $PH_3$ and $NaH_2PO_2$. This reaction is an example of

What is meant by 'disproportionation' of an oxidation state? Give an example.

$1 \text{ mole}$ of $MnO_4^{2-}$ disproportionates into $MnO_4^-$ and $MnO_2$ in an acidic medium. Calculate the percentage by mass of $Mn$ converted to $MnO_4^-$ (Molar mass of $Mn = 55 \ g/mol$).

Which of the following represents the disproportionation of potassium chlorate?
