Question

why is H2O2 not stored in glass bottles?how is it stored?
​

Answer 1

The packaging of hydrogen peroxide in brown bottles is essential to ensure that it retains its chemical properties. ... This is why plastic bottles or glass bottles coated with wax are used instead. The brown tint of the bottle prevents light being absorbed by the solution, preventing the oxidation and reduction reaction.

Answer 2

Hydrogen peroxide (H₂O₂) is not stored in glass bottles because they are transparent and light can easily penetrate through these glass bottles to oxidize into water and oxygen gas. It is recommended that hydrogen peroxide is stored in brown bottles or glass bottles coated with wax to avoid absorption of light by the solution; thereby, preventing the oxidation and reduction reaction.
