Write chemical reactions to show the atmospheric nature of water.

Solution
The atmospheric nature of water can be described on the basis of the following reactions:
(1) Reaction with H2S The reaction takes place as:
H2O(l)Base+H2S(aq)Acid⇌H3O+(aq)Conjugate acid+HS−(aq)Conjugate base
In the forward reaction, H2O(l) accepts a proton from H2S(aq). Hence, it acts as a Brønsted-Lowry base.
(2) Reaction with NH3
The reaction takes place as:
In the forward reaction, H2O(l) denotes its proton to NH3(aq). Hence, it acts as a Brønsted-Lowry acid.
(3) Self-ionization of water.
In the reaction, two water molecules react as:
In the forward reaction, H2O(l) denotes its proton to H2O(l). Hence, it acts as an amphoteric solution.
