Assertion : `H_(2)O_(2)` is stored in wax-lined glass or plastic vessels.
Reason : `H_(2)O_(2)` decomposes slowly on exposure to light.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(2)O_(2)` decomposes slowly on exposure to light. `2H_(2)O_(2(l))to 2H_(2)O_((l))+O_(2(g))`
In the presence of metal surfaces or traces of alkali (present in glass containers), the above reaction is catalysed. Hence, `H_(2)O_(2)` is stored in wax-lined glass or plastic containers in dark.
