Sodium peroxide which is a yellow solid , when exposed to air becomes white due to the formation of

A

`H_2O_2`

B

`Na_2O`

C

`Na_2O` and `O_3`

D

NaOH and `Na_2CO_3`

Text Solution

Verified by Experts

The correct Answer is:
D

In presence of moisture and `CO_2` present in air, `Na_2O_2` is converted into NaOH and `Na_2CO_3` respectively both of which are white
`Na_2O_2 +H_2O rarr 2NaOH+H_2O_2`
`2Na_2O_2+2CO_2 rarr 2Na_2CO_3 +O_2`
or `Na_2O_2 +H_2O+CO_2 rarr Na_2CO_3 +H_2O_2`
