Question

If pH of a saturated solution of Pb(OH)2 is 9 then the value of solubility of Pb(OH)2 is
​

Answer 1

Explanation:

.. pOH = 6

or [OH-] = 10-6

Now left solubility of Pb(OH), be S mol litre¯¹ in

it.

2+ 2 Thus, [Pb²+] [OH-]² = KSP

612

Answer 2

Answer: The solubility of Pb(OH)2 in water can be determined by considering the pH of a saturated solution of the compound.

Explanation:

If the pH of the solution is 9, it indicates that the solution is basic and that Pb(OH)2 has dissociated into its component ions, Pb2+ and OH-.

The solubility of Pb(OH)2 is directly proportional to the concentration of hydroxide ions in the solution. In a basic solution, the concentration of hydroxide ions is high, which means that Pb(OH)2 is highly soluble. On the other hand, in an acidic solution, the concentration of hydroxide ions is low, and as a result, Pb(OH)2 is less soluble.

It is also important to note that the solubility of Pb(OH)2 can be influenced by temperature. Generally, an increase in temperature can increase the solubility of a solid in a solvent. Conversely, a decrease in temperature can decrease the solubility of a solid in a solvent.
