Why does adding sodium chloride to a saturated solution of lead chloride reduce the solubility of pbvi2?

B) Equilibrium is pushed towards the left in the equation

PbCl2 -> Pb+2 + 2Cl-

Explanation:

We have a saturated solution of PbCl2. It means the maximum amount of PbCl2 is dissolved in the solution. If we add sodium Chloride - NaCl, the solubility will be reduced.

NaCl will dissolve into the solution forming Na+ and Cl- ions. Cl- ions are common for the PbCl2 and NaCl. The effect of increasing Cl- ions due to the NaCl will reduce the solubility of PbCl2.

It means if we add Cl- ions or Pb+2 ions independent from the component apportioning them, the solubility will be reduced for the PbCl2, and the equilibrium will be pushed towards the left in the equation

PbCl2 -> Pb+2   + 2Cl-

Finally, we can conclude that the answer is B) Equilibrium is pushed towards the left in the equation:

PbCl2 -> Pb+2   + 2Cl-

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
