Explain why hydrogen peroxide is stored in coloured`//`plastic botles?

Explanation

`H_(2)O_(2)` decomposes slowly on exposure to light.
`2H_(2)O_(2(l))to2H_(2)O_(l)+O_(2(g))`
In the presences of metal surfaces or traces of alkali present in glass bottles, the above decomposition reaction is catalysed. Hence, it is stored in coloured/plastic bottles in dark. As a stabiliser, urea can be added. dust also induces explosive decomposition
