9.24. Water is amphoteric in nature because it acts as an acid as well as a base.
Amphoteric nature of water is represented by following chemical reactions.
(1) Water as a base:
H2?O(l)+H2?S(g)?H3?O+(aq)+HS−(aq)(2) Water as an acid:
H2?O(l) +NH3?(aq)?OH−+NH4+?(3) Self ionization of water in which water simultaneously acts as acid and base.
2H2?O→H
