Literally hydrolysis means breakage by water. We know that when an acid and a base react with each other a salt plus water is formed: AH +BOH <–> AB + H 2 O. It is conceivable that if the process is reversible, i.e., that when a salt dissolves in water, an acid or base may appear in the medium, assigning it a certain pH. AB + H 2 O <–> AH ...
