Which is not the hydrolysis reaction?

Hydrolysis is the interaction of  cation or anion or both of a salt (or organic ester, etc) to form acidic/basic/neutral solution.Salt of strong acid and strong base is not hydrolysed Thus, or NaCl (salt of strong acid (HCI) and strong base (NaOH)) does not react with H2O. (b) CH3COO−+H2O⇌CH3COOH Weak acid +OH− Basic  (c) Cu2++2H2O⇌Cu(OH)2week base+2H+ Acidic  (d) CH3COOC2H5+H2O⇌CH3COOH+C2H5OHCH3COOH>C2H5OH (acid) Hence, solution is acidic
