प्रश्न
Water acts as Bronsted acid as well as a Bronsted base. Give one example each to illustrate this statement.
उत्तर
\[\ce{\underset{\text{Bronsted acid}}{H2O} + \underset{\text{Bronsted base}}{NH3} ⇌ {NH_4^+} + {OH^-}}\]
\[\ce{\underset{\text{Bronsted acid}}{HCl} + \underset{\text{Bronsted base}}{H2O} ⇌ {H3O^+} + {Cl^-}}\]
