Salt X = Salt of weak base
Cations that undergo hydrolysis produce acidic solutions. A cation causes hydrolysis by bonding to the hydroxide part of the water molecule.
 
M+ + HOH → H+ + MOH

For example: Ammonium chloride
 
 
Salt Y = Salt of weak acid
Anions that undergo hydrolysis produce basic solutions. An anion can cause hydrolysis by acting as a Brønsted base.
 
A– + HOH → HA + OH–
 
For example: Sodium acetate
