In which of the following reactions does NH_(3) act as a acid?

Answer»

`NH_(3)+H^(+)rarrNH_(4)`
`NH_(3)+H^(+)rarrNH_(2)^(-)+H_(2)`
`NH_(3)+HClrarrNH_(4)CL`
None as `NH_(3)` is a base

Solution :In the REACTION ,`NH_(3)` CHANGES to `NH_(2)^(-)` so `NH_(3)` has donated a proton `(H^(+))` and hence ACTS as an acid.
