Write the chemical reactions to show the amphoteric nature of water. |
|
Answer» Solution :WATER is AMPHOTERIC in NATURE and it behaves both as an acid as well as base. With acids STRONGER than itself (eg. `H_(2)S`) it behaves as a base and with bases stronger than itself (eg, `NH_(3)`) it acts as an acid. (i) As a base: `H_(2)O_((L))+H_(2)S_((aq))toH_(3)O_((aq))+HS^(-)` (ii) As an acid: `H_(2)O_((l))+NH_(3(aq))toOH_((aq))^(-)+NH_(4(aq))^(+)` |
