The student placed 10 ml of pbcl2 (saturated solution) in the test tube and added a pinch of nacl. a white precipitate of pbcl2 formed. how will this affect the concentration of pb+2?

Concentration of decreases

Explanation:

In a saturated solution of , the following solubility equilibrium exist-

Now, NaCl contains common ion . Therefore, concentration of increases in solution.

But, at a particular temperature, equilibrium constant remain constant. Therefore to keep equilibrium constant same will reacts with excess to decrease concentration of .

Therefore concentration of decreases.

Note: Equilibrium constant for the above equilibrium=
