Question

CaCO3(s) Ca2+(aq) + CO32-(aq)the addition of which component will cause a shift in equilibrium because of a common ion effect ​

Answer 1

Answer:

Recognize common ions from various salts, acids, and bases.Calculate concentrations involving common ions.Calculate ion concentrations involving chemical equilibrium.The common-ion effect is used to describe the effect on an equilibrium involving a substance that adds an ion that is a part of the equilibrium. Common IonsWhen NaCl and KCl are dissolved in the same solution, the Cl− ions are common to both salts. In a system containing NaCl and KCl , the Cl− ions are common ions.NaCl⇌Na++Cl− KCl⇌K++Cl− CaCl2⇌Ca2++2Cl− AlCl3⇌Al3++3Cl− AgCl⇌Ag++Cl−
