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

Answer:

Auto-protolysis (self-ionization) of water is a chemical reaction in which two water molecules react to produce a hydroxide ion (OH^-) and a hydronium ion (H3O+).

The reaction involved can be represented as:

Auto-protolysis of water indicates its amphoteric nature i.e., its ability to act as an acid as well as a base. The acid-base reaction can be written as:
