प्रश्न
What do you understand by the term ‘auto protolysis of water’ ? What is its significance?
उत्तर
Autoprotolysis is a reaction in which two same molecules react to give ions with proton transfer. Water undergoes autoproteolysis, i.e., a proton from one molecule is transferred to another molecule.
\[\ce{H2O (l) + H2O (l) ⇌ H3O+ (aq) + OH- (aq)}\]
On account of autoprotolysis, water is amphoteric in nature.
