The concentration of which ion is to be decreased, when `NH_(3)` solution is added

A

`OH^(-)`

B

`NH_(4)^(+)`

C

`H_(3)O^(+)`

D

`O_(2)^(-)`

Text Solution

Verified by Experts

The correct Answer is:
C
`NH_(3)` acts as a Lewis base and can give an electron pair to `H_(3)O^(+)` so its concentration will decrease.
