Sodium peroxide which is a yellow solid,...

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

A

NaOH and `Na_(2)CO_(3)`

B

NaOH and `H_(2)O_(2)`

C

`Na_(2)O` and `O_(3)`

D

`Na_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
A

Sodium peroxide is a plate yellow powder. On exposure, it becomes white as if reacts with moisture and carbon dioxide:
`2Na_(2)O_(2)++2H_(2)Orarr4NaOH+O_(2)`
`2Na_(2)O_(2)+2CO_(2)rarr2Na_(2)CO_(3)+O_(2)`
