Greater the `pK_(a)` value on an acid `……………` is the acid .

How are pK_(a) values related to acid strength of an acid?

The pK_(a) for acid A is greater than pK_(a) for acid B, the strong acid is :-

The pK_(a) for acid A is greater than pK_(a) for acid B, the strong acid is :-

pK_(a) of a weak acid is defined as :

Account for the following : (a) Aromatic carboxylic acids do not undergo Friedel-Crafts reaction. (b) pK_(a) value of 4-nitrobenzoic acid is lower than that of benzoic acid .

Chloroacetic acid has lower pK_(a) value than acetic acid.

The pH of 0.1M monobasic acid is 4.50 . Calculate the concentration of species, H^(o+), A^(Θ) , and HA at equilibrium. Also determine the value of K_(a) and pK_(a) of the monobasic acid.

If the pK_(a) of a weak and acid HA is 4.80 and the pK_(b) of a weak base BOH is 4.78. Then, the pH of an aqeuous solution of the corresponding salt, BA will be
