The acidic nature of an aqueous solution of $FeCl_3$ is due to:

Assertion: The aqueous solution of $FeCl_3$ is basic in nature.
Reason: $FeCl_3$ hydrolyses in water.

Calculate the percentage of hydrolysis in $0.01 \ M$ aqueous solution of $NaOCN$ ($K_b$ for $OCN^{-} = 10^{-10}$)

The dissociation constant of a substituted benzoic acid at $25^{\circ}C$ is $1.0 \times 10^{-4}$. The $pH$ of a $0.01 \ M$ solution of its sodium salt is

What is the $pH$ of a $K_2S$ solution?

Which of the following is a basic salt?
