Q: 46. The ionization constant of acetic acid is Calculate the degree of dissociation of acetic acid in its 0.05 M solution. Calculate the concentration of acetate ion in the solution and its pH.

Structure of Ionization Constant of Acetic Acid

Answer:

Method 1

(1)

(2)

Since :

Method 2

Degree of dissociation,

Then,

Thus, concentration of

Since

Hence, the concentration of acetate ion in the solution is 0.00093 M and its pH is .

Q: 47. It has been found that the pH of a 0.01 M solution of an organic acid is . Calculate the concentration of the anion, the ionization constant of the acid and its

Answer:

Let the organic acid be HA.

Concentration of HA = 0.01 M

Then,
