1) What is the common ion effect? Select all that apply.
a) The increase in solubility that occurs when a common ion is added to a saturated solution of a sparingly soluble ionic compound.
b) The decrease in solubility that occurs when a common ion is added to a saturated solution of a sparingly soluble ionic compound.
c) The increase in solubility that occurs when a common ion is added to a unsaturated solution of a sparingly soluble ionic compound.
d) None of these.
2) How does Le Châtelier's principle explain it? Select all that apply.
a) Addition of an ion to a saturated solution will shift the equilibrium so as to absorb as much of the added ion as possible.
b) Addition of an ion to a saturated solution will shift the equilibrium so as to produce as much of the added ion as possible.
c) Addition of an ion to a saturated solution will shift the equilibrium so as to produce more solid.
d) Addition of an ion to a saturated solution will shift the equilibrium so as to dissolve more solid.
e) None of these.
