HA + BOH → BA + H2O
Depending on the solubility of the salt, it may remain in ionized form in the solution or it may precipitate out of solution. Neutralization reactions usually proceed to completion.
The reverse of the neutralization reaction is called hydrolysis.
In hydrolysis reaction, a salt reacts with water to yield the acid or base:
BA + H2O → HA + BOH
From reactions involved we can observe that hydrolysis is opposite of neutralization.
