First, you need to define what hydrolysis is. Hydrolysis is the decomposition of a complex substance under the influence of water.
NaCl – does not hydrolyze, because NaOH is a strong base and HCl is a strong acid.
Li2SO4 – does not hydrolyze, because LiOH is a strong base and H2SO4 is a strong acid.
BaSO4 – does not hydrolyze, because Ba (OH) 2 is a strong base and H2SO4 is a strong acid.
KNO2 – hydrolyzes, because KOH is a strong base and HNO2 is a weak acid. (hydrolysis by anion)
