# How addition of a soluble salt affects equilibrium involving precipitation with a base sharing the same cation?

I have the following reaction at equilibrium:

$$\ce{Ba(NO3)2(aq) + KOH(aq) <=> Ba(OH)2(s) + 2 KNO3(aq)}$$

Will there be a change in the equilibrium if the salt $$\ce{KCl}$$ is added? Will the reaction shift in a certain direction to restore equilibrium?

I know that with adding $$\ce{KCl}$$, $$\ce{K+}$$ ions are added, but I am not sure if that is related to the answer.

• Start by writing the net ionic equation.
