Which of the following statements is TRUE of a saturated solution? The solution is completely homogeneous. None of the other statements are true. The concentration of the reactants and products are equal. If additional solute is added to the solution, it readily dissolves. The rate at which solute dissolves is equal to the rate at which the solid forms.
