When `CO_(2)` is bubbled throgh a solution of barium peroxide in water

A

carbonic acid is formed

B

`H_(2)O_(2)` is formed

C

`H_(2)O` is formed

D

barium hydroxide is formed.

Text Solution

Verified by Experts

The correct Answer is:
B
When `CO_(2)` is bubbled through a cold solution of barium peroxide in water, `H_(2)O_(2)` is obtained. `BaO_(2)+CO_(2)+H_(2)O to BaCO_(3) darr +H_(2)O_(2)`
