# Nucleophilic addition reaction of ketone to form alcohol - no acid treatment?

I'm preparing for a chem prac on reduction of a ketone group (in particular, the C=O in benzoin) using a nucleophilic addition reaction.

In the experimental method, all we do is react benzoin with $\ce{NaBH4}$, the nucleophile. The solvent we're using is a mix of ethanol/water. From what I've learned, the reaction forms a $\ce{C-O^-}$ alkoxide group which then needs to grab a proton from something to form the alcohol.

In the procedure, we mix ethanol/water, and that's it - no addition of dilute acid to then protonate the alkoxide. We're told to add hot water. Am I right in saying that addition of hot water provides a source of protons to protonate the alkoxide?

Thanks :)
