Question

Which statements are true concerning a saturated solution of pbcl2? (select all that apply.) pbcl2(s) pb2+ + 2cl- the system is in equilibrium. the rate of dissolving is equal to the rate of recrystallization. the concentration of pbcl2 is greater than normal. the product [pb2+][cl-]2 equals ksp?

Answer 1

The system is in equilibrium
The rate of dissolving is equal to the rate of recrystallization
The product [Pb2+][Cl-]2 equals Ksp

Answer 2

In a saturated solution of PbCl₂:

Follows the equation:

PbCl₂----->Pb²⁺ + 2Cl⁻

The saturated solution signifies all these information:

1. The system is in equilibrium.

2. The rate of dissolving is equal to the rate of recrystallization.

3. The product [Pb²⁺][Cl⁻]² equals ksp.

So here only point 3 is incorrect that is the concentration of PbCl₂ is greater than the normal.
