<p><span data-teams="true">This is a short answer type question as classified in NCERT Exemplar</span></p><p>Self ionization of water is known as autoprotolysis of water.</p><p>H₂O (l) &nbsp; &nbsp; + &nbsp;&nbsp;&nbsp;&nbsp; H₂O (l) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; → &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; H₂O₂ (aq) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; + &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; OH^- (aq)</p><p>Acid&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Base &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Conjugate acid &nbsp; &nbsp; &nbsp; &nbsp; Conjugate acid</p><p>Significance of autoprotolysis: Due to autoprotolysis, water has the ability to act as an acid as well as a base. Thus, it behaves as an amphoteric substance.</p><p>H₂O (l)+NH₃ (aq) ↔ OH^- (aq)+NH₄⁺ (aq)</p><p>H₂O (l)+H₂ (aq) ↔ H₃O⁺ (aq)+HS^- (aq)</p>
