The solution of $Na_2CO_3$ has $pH$:

What will be the $pH$ and $\alpha$ (degree of hydrolysis) respectively for the salt $BA$ of $0.1 \ M$ concentration? (Given: $K_a$ for $HA = 10^{-6}$ and $K_b$ for $BOH = 10^{-6}$)

If a $0.01 \ M \ NaCN$ solution is $3.37 \%$ hydrolyzed,calculate the value of $K_h$.

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

When $1 \ mol$ of aniline hydrochloride is dissolved in $99.2 \ L$ of water,the degree of hydrolysis is $4.88 \%$. Calculate the hydrolysis constant $(K_h)$.

The $pK_a$ of a weak acid $(HA)$ and $pK_b$ of a weak base $(BOH)$ are $3.2$ and $3.4$ respectively. Find the $pH$ of their salt $(AB)$.
