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

Which salt represents the highest degree of hydrolysis?

Which of the following salts when dissolved in water will get hydrolysed?

The approximate $pH$ of $0.01 \ M \ NaHA$ is calculated by: ($K_{a_1} = 10^{-6}$ and $K_{a_2} = 10^{-8}$ are ionization constants of $H_2A$)

$NH_4CN$ is a salt of a weak acid $HCN$ $(K_a = 6.2 \times 10^{-10})$ and a weak base $NH_4OH$ $(K_b = 1.8 \times 10^{-5})$. $A$ $1 \ M$ solution of $NH_4CN$ will be:

Aqueous solutions of $1 \ M$ potassium acetate and $1 \ M$ potassium formate are taken in separate beakers. Which of the following relationships is correct?
