Assume that five weak acids, identified only by numbers (1, 2, 3, 4, and 5) have the following ionization constants: A1 - Ka = 1.0 x 10-3 A2 - Ka = 3.0 x 10-5 A3 - Ka = 2.6 x 10-7 A4 - Ka = 4.0 x 10-9 A5 - Ka = 7.3 x 10-11

Complete question:

Assume that five weak acids, identified only by numbers (1, 2, 3, 4, and 5) have the following ionization constants: A1 - Ka = 1.0 x 10-3 A2 - Ka = 3.0 x 10-5 A3 - Ka = 2.6 x 10-7 A4 - Ka = 4.0 x 10-9 A5 - Ka = 7.3 x 10-11

The anion of which acid is the strongest base? a) A2 b) A5 c) A3 d) A1 e) A4

(B) The anion with the strongest base is A5

Explanation:

Acidity of a solution depends on the concentration of H⁺

Assuming a constant solution molarity (HA), then

                                               pH = -Log{H⁺]

For A1: ,             pH = 1.5

For A2: ,          pH = 2

For A3:       pH = 3

For A4:        pH = 4

For A5:  pH = 5

From the calculation above, the strongest acid is A1 and the weakest Acid is A5.

Therefore, the anion with the strongest base is A5

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
