In a salt "x", the cation is said to undergo hydrolysis. In a salt "y", the anion is said to undergo hydrolyis.Explain with reason and explain the nature of the above solutions.
I don't even understand the question.Please explain what is hydrolyis?How does an anion or a cation undrgo hydrolysis?Give some examples.

Expert Answer:

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
