      What do you understand by the term 'auto protolysis  of water'? What is its significance?

    Answer:

      Autoprotolysis is a reaction in which two same molecules react to give ions with proton transfer. Water undergoes autoprotolysis, i.e., a proton from one molecule is transferred to another molecule. \[{{H}_{2}}O(l)+{{H}_{2}}O(l)\underset{{}}{\leftrightarrows}{{H}_{3}}{{O}^{+}}(aq.)+O{{H}^{-}}(aq)\] On account of autoprotolysis, water is amphoteric in nature.
