Acid-base concepts and pH scale 27

Ionisation of weak acids and bases, Ostwald dilution law 28

A weak monobasic acid HA is 1% ionised in a 0.1 M solution. Taking K_a = calpha^2, the value of K_a is
When a solution of a weak electrolyte is diluted at constant temperature, the degree of ionisation and the ion...
The degree of ionisation of a weak acid in 0.1 M solution is 0.02. Assuming alpha ll 1, its degree of ionisati...
Four monobasic weak acids have the following pK_a values. Which value belongs to the strongest acid?
The pH of a 0.01 M solution of a weak monobasic acid with K_a = 1x10^-6 is (use [H+] = sqrtK_a c)
The percentage ionisation of a 0.01 M weak base with K_b = 1x10^-6 is (use alpha = sqrtK_b/c)
Find the pH of 0.05 M acetic acid (K_a = 1.8x10^-5), using [H+] = sqrtK_a c. Give two decimals.
A 0.2 M solution of a weak monobasic acid HA has pH 3.00. Neglecting the amount ionised compared with 0.2 M, K...
