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

  • chemistry -

    What do you think the correct answer is and why?

  • chemistry -

    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.
