Answer 2

Step-by-step explanation:

Self-ionization of water is defined as the reaction where a water molecule deprotonates in order to change into a hydronium ion and hydroxide ion.

For example,
`H_(2)O + H_(2)O \rightarrow H_(3)O^(+) + OH^(-)`

So, here hydroxide ion (
`H_(3)O^(+)`) is formed along with the formation of hydroxide ion, that is,
`OH^(-)`.

Thus, we can conclude that the equation
`H_(2)O + H_(2)O \rightarrow H_(3)O^(+) + OH^(-)` correctly expresses the self-ionization of water.
