Question

state common ion effect on solubility? The value of kp for reaction
​

Answer 1

Answer:

If you have a solution and solute in equilibrium, adding a common ion (an ion that is common with the dissolving solid) decreases the solubility of the solute. This is because Le Chatelier's principle states the reaction will shift toward the left (toward the reactants ) to relieve the stress of the excess product.
