ChemistrySingle correct+4 / -1Question 43 of 90

From the following statements regarding $\ce{H2O2}$ , choose the incorrect statement :

It can act only as an oxidizing agent

It decomposes on exposure to light

It has to be stored in plastic or wax lined glass bottles in dark

It has to be kept away from dust

Answer and worked solution

Official answer: A

$\ce{H2O2}$ acts as both an oxidising and a reducing agent (it reduces $\ce{MnO4-}$ , for example), so "only as an oxidizing agent" is incorrect. The other three statements are correct storage and stability facts.

Topics:Water and hydrogen peroxide
