Question
From the following statements regarding H2O2, choose the incorrect statement :
Options
A.It has to be stored in plastic or wax lined glass bottles in dark
B.It has to be kept away from dust
C.It can act only as an oxidizing agent
D.It decomposes on exposure to light
Solution
(1) H2O2 to be stored in plastic or wax lined glass in dark because, traces of alkali (present in glass) strongly catalyse the decomposition of H2O2 H2O2 → H2O + 1/2 O2
(2) H2O2 to be kept away from dust because dust induces explosive decomposition of H2O2.
(3) H2O2 can act as oxidising agent as well as reducing agent depending on condition, because the oxidation state of O-atom in H2O2 is −1. Which is in between highest (+2) and lowest (−2) oxidation state of O-atom.
(4) H2O2 decomposes in presence of light H2O2
H2O + 1/2 O2
(2) H2O2 to be kept away from dust because dust induces explosive decomposition of H2O2.
(3) H2O2 can act as oxidising agent as well as reducing agent depending on condition, because the oxidation state of O-atom in H2O2 is −1. Which is in between highest (+2) and lowest (−2) oxidation state of O-atom.
(4) H2O2 decomposes in presence of light H2O2
