Question

Using a value of Ksp = 1.8 x 10-2 for the reaction PbCl2 (s) Pb+2(aq) + 2Cl -(aq).

The concentration of the products yield a Ksp of 2.1 x 10-2:

Ions are recombining to form a solid precipitate.
The concentration of the products is expected to decrease.
The concentration of the products is expected to increase.
The concentration of PbCl2is expected to increase.
It is not possible to have a system with Ksp> 1.8 x 10-2.
