Liquid `N_(2)O_(4)`is a useful nonaqueous solvent in which

Options

A. both `NO^(+)` and `NO_(3)^(-)` salts are acids
B. both `NO^(+)` and `NO_(3)^(-)` salts are bases
C. `NO^(+)` salts are acids and `NO_(3)^(-)` salts are bases
D. `NO^(+)` salts are bases and `NO_(3)^(-)` salts are acids.

Answer

3

Explanation

Liquid dinitrogen tetroxide, useful as a non-aqueous solvent, self ionizes slightly into`NO^(+)` and`NO_(3)^(-)` ions.
`N_(2)O_(4) hArr NO^(+)+NO_(3)^(-)`
In`N_(2)O_(4)` substance contaninig `NO^(+)` are acids and those containing `NO_(3)^(-)` are bases. Thus, a typical acid-base reaction is
`underset("acid")(NOCl)+underset("base")(NH_(4)NO_(3))-underset("salt")(NH_(4)Cl)+underset("Solvent")(N_(2)O_(4))`
