- #24Write chemical reactions to show the amphoteric nature of water.
Ans : The amphoteric nature of water can be described on the basis of the following reactions:
1) Reaction with H2S
The reaction takes place as:
In the forward reaction,
accepts a proton from
. Hence, it acts as a Lewis base.
2) Reaction with NH3
The reaction takes place as:
In the forward reaction, denotes its proton to
. Hence, it acts as a Lewis acid.
3) Self-ionization of water
In the reaction, two water molecules react as:
