How the H_2O_2 should be store ?

Answer»

Solution :`H_2O_2` decomposes slowly on exposure to LIGHT.
`2H_2O_(2(l)) to 2H_2O_((l))+ O_(2(g))`
In the presence of METAL surfaces or traces of alkali (present in glass containers), the above reaction is catalysed.
It is, therefore, stored in wax-lined glass or plastic vessels in dark. Urea can be added as a stabiliser. It is kept away from dust because dust can INDUCE explosive decomposition of the compound.
