Arrange `NH_(4)^(+), H_(2)O, H_(3)O^(+), HF` and `OH^(-)` in increasing order of acidic nature:

Options

A. `H_(3)O^(+) lt NH_(4)^(+) lt HF lt OH^(-) lt H_(2)O `
B. `NH_(4)^(+) lt HF lt H_(3)O^(+) lt H_(2)O lt OH^(-)`
C. `OH^(-) lt H_(2)O lt NH_(4)^(+) lt HF lt H_(3) O^(+)`
D. `H_(3)O^(+) gt HF gt H_(2)O gt NH_(4)^(+) gt OH^(-)1`

Answer

C

Explanation

`H_(3)O^(+) gt HF gt NH_(4)^(+) gt H_(2)O gt OH^(-)`
Acidic nature in decreasing order.
