Question

explain the hydrolysis of a salt​

Answer 1

Answer:

Salt hydrolysis is defined as the process in which a salt reacts with water to give back the acid and the base. ... This is called acidic hydrolysis. Salt hydrolysis may be defined as the reaction of the cation or the anion of the salt with water to produce acidic or basic solution.

Answer 2

» Salt hydrolysis is a phenomenon in which the anion or cation or both of a salt react with water and producing acidic solution or basic solution or both in aqueous solutions.

$\bigstar$ Anionic hydrolysis gives solution with Ph greater than 7.

Example :

$\sf CH_3COO^- + H_2O \leftrightarrow CH_3COOH + OH^-$

$\bigstar$ Cationic hydrolysis gives acidic solutions with Ph less than 7.

Example :

$\sf NH_4 + H_2O \leftrightarrow NH_4OH + H^+$

$\bigstar$ Salt of strong acid and strong base do not hydrolyzed and the solution is neutral pH is equal to 7

Example : NaCl, NaNO₃
