When 1 F of electricity is passed through acidulated water `O_(2)` evolved is

A

`11.2 dm^(3)`

B

`5.6 dm^(3)`

C

`22.4 dm^(3)`

D

`1.0 dm^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`1F -= 1g`. Eq of `O^(2-)` ion `-= 8g` of `O^(2-)` ion `-= 1/4` mole of `O_(2)` gas `-= 1/4 xx 22.4 L` of `O_(2)` gas `-=` 5.6 L of `O_(2)` gas.
