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

Options

A. `H_(2)O_(2)`
B. `Na_(2)O`
C. `Na_(2)O and O_(3)`
D. `NaOH and Na_(2)CO_(3)`

Answer

D

Explanation

In presence of moisture and `CO_(2)` present in air , `Na_(2)O_(2)` is converted into NaOH and `Na_(2)CO_(3)` respectively both of which are white
`Na_(2)O_(2) + H_(2) O to 2 NaOH + H_(2)O_(2)`
`2 Na_(2) O_(2) + 2 CO_(2) to 2 Na_(2) CO_(3) + O_(2)`
or `Na_(2)O_(2) + H_(2)O + CO_(2) to Na_(2)CO_(3) + H_(2)O_(2)`
