What happens with enol and ketone
Because the enol and ketone aren't stable, equilibrium happens; therefore the enol has a chance of losing a hydrogen ion and because of that, the enol becomes an enolate.

Also keep in mind that an acid is a molecule that can donate a proton.
The enolate is a base and it's gathering/accepting a proton from the hydrogen.

I assume this is what you meant when you asked the question.
