Solution of `K_(2)O` in water in basic, because it contains a significant concentration of

A

`O_(2)^(-)`

B

`O^(3-)`

C

`OH^(-)`

D

`K^(+)`

Text Solution

Verified by Experts

The correct Answer is:
C
`K_(2)O+H_(2)Orarr2KOH`
The resulting solution is basic due to the presence of `OH^(-)` from KOH.
