The process in which like molecules react with each other to yield ions is called:

1. Water is both a very weak acid and a very weak base. 2. So two water molecules can react with each other. 3. The process in which like molecules react to yield ions is called autoionization. 4. It is what gives pure water its small but non-zero conductivity. _Source: OpenStax Chemistry 2e (CC BY 4.0), Ch 14 'Acid-Base Equilibria', sections 14.1-14.7_
