The aqueous solution of sodium acetate is:

$NaCl$ does not undergo hydrolysis because......

$NH_4Cl$ is acidic,because

What is the correct relationship between the $pH$s of isomolar solutions of sodium oxide $(pH_1)$,sodium sulphide $(pH_2)$,sodium selenide $(pH_3)$ and sodium telluride $(pH_4)$?

Which of the following salts on dissolution in water gives $pH$ less than $7$ at $298 \ K$?

The degree of hydrolysis of a salt of weak acid and weak base in its $0.1 \, M$ solution is found to be $50 \%$. If the molarity of the solution is $0.2 \, M$,the percentage hydrolysis of the salt should be $...... \%$.
