If $pK_b$ for fluoride ion $(F^-)$ at $25\,^{\circ}C$ is $10.83$,the ionisation constant $(K_a)$ of hydrofluoric acid $(HF)$ in water at this temperature is:

The $pK_a$ for acid $A$ is greater than $pK_a$ for acid $B$. The strong acid is

The conjugate acid of a strong base is a

The $K_a$ of $CH_3COOH$ is $1.76 \times 10^{-5}$ at $298 \ K$. Calculate the dissociation constant $(K_b)$ of its conjugate base.

Which species acts as an acid in the reaction $CH_{3}COOH_{(aq)} + H_{2}O_{(l)} \rightleftharpoons H_{3}O^{+}_{(aq)} + CH_{3}COO^{-}_{(aq)}$?
