(2015 Main)

(a) It can act only as an oxidising agent

(b) It decomposed on exposure to light

(d) It has to be kept away from dust

Show Answer

Solution:

$H_{2} O_{2}$ acts as an oxidising as well as reducing agent, because oxidation number of oxygen in $H_{2} O_{2}$ is -1 . So, it can be oxidised to oxidation state 0 or reduced to oxidation state -2 .

$H_{2} O_{2}$ decomposes on exposure to light. So, it has to be stored in plastic or wax linked glass bottles in dark for the prevention of exposure. It also has to be kept away from dust.
