What is meant when it is stated that WATER can ""Ionize"" to a certain extent? What are the products that are formed when water ionizes? What is the pH of pure water?

Ionization is defined as the process by which the atoms accept or donate electrons and form positively or negatively charged species, called ions.

The ionization of water is known as the self-ionization or autoionization of water. This process involves the deprotonation of a water molecule and protonation of another water molecule to give hydroxide ion and hydronium ion, which exist in the state of chemical equilibrium.

H₂O + H₂O ⇌ H₃O⁺ + OH⁻

The pH of pure water is 7, neutral.
