Which of the following is not true in a dynamic equillibrium describing a saturated solution?

Choose one answer. a. solid crystalizes from solution
b. solid dissolves in the solution
c. concentration of dissolved solute remain constant
d. rate of dissolving is double the rate of crystallization

What do you think the correct answer is and why?

I thought it was b. solid dissolves in the solution because in dynamic equil I thought that the excess ionic solute pass through the solution continuously as htdrated ions are deposited on surface of solute So the solid I though would dissolve in solution and add to solution.

In a saturated solution, solid is continuously dissolving in the liquid (a is true), crystals are continuously forming from the solution onto the old crystals (b is true), since the solid dissolving and the crystals coming out of solution are occurring at the same rate (c is true), then d must be the statement that is NOT true. And it isn't, The crystals going into solution and the crystals coming out of solution occur at the same rate. As a result, the concentration of the material in solution remains constant.

To determine which statement is not true in a dynamic equilibrium describing a saturated solution, let's analyze each option:

a. Solid crystalizes from solution: In a saturated solution, the concentration of the dissolved solute is at its maximum. Any additional solute introduced to the solution will not dissolve and will instead form solid crystals. Therefore, this statement is true.

b. Solid dissolves in the solution: In a dynamic equilibrium, the rate of dissolving and crystallization are equal. As the solid solute dissolves, an equal amount of solute will crystallize back into the solid form. Therefore, this statement is true.

c. Concentration of dissolved solute remains constant: In a saturated solution, the concentration of dissolved solute remains constant because the rate of dissolving and crystallization are equal. Therefore, this statement is true.

d. Rate of dissolving is double the rate of crystallization: In a dynamic equilibrium, the rate of dissolving is equal to the rate of crystallization. The solution reaches a point where the rates are balanced, and no further net change occurs. Therefore, this statement is not true.

Therefore, the correct answer is d. The rate of dissolving is not double the rate of crystallization in a dynamic equilibrium describing a saturated solution.
