Chemistry Class 11 NCERT Solutions Chapter 7 Equilibrium Part 26

Q: 67. Determine the solubilities of silver chromate, barium chromate, ferric hydroxide, lead chloride, and mercurous iodide at 298K from their solubility product constants given in Table (page ). Determine also the molarities of individual ions.

Answer:

(1) Silver chromate:

Then,

Let the solubility of be S.

Then,

(2) Barium chromate:

Then,

Let be the solubility of

Thus, =s and = s

Molarity of

(3) Ferric hydroxide;

Let s be the solubility of .

Thus,

Molarity of

Molarity of

(4) Lead chloride:

Let be the solubility of

Thus,

Molarity of chloride

(5) Mercurous iodide

Let be the solubility of

Thus,

Molarity of

Molarity of
