(a)
Interpretation:
The substance that would pass through the given bag into the surrounding water is to be predicted.
Concept introduction:
Semipermeable membranes are the membrane that selectively allows some substance to pass through it. The pores present in the semipermeable membrane that acts as a dialyzing membrane is large enough to allow the movement of water, hydrated ions, and other small molecules.

- Refer to Figure 13.10 ( Sec. 13-4b) to answer these questions. (a) Does a saturated solution occur when 65.0 g LiCl is present in 100 g H2O at 40 C? Explain your answer. (b) Consider a solution that contains 95.0 g LiCl in 100 g H2O at 40 C. Is the solution unsaturated, saturated, or supersaturated? Explain your answer. (c) Consider a solution that contains 50. g Li2SO4 in 200. g H2O at 50 C. Is this solution unsaturated, saturated, or supersaturated? Explain your answer.

- . Why does the amount of excess solid solute present in a solution not affect the amount of solute that ultimately dissolves in a given amount of solvent?arrow_forwardClassify each of the following solutions as saturated, unsaturated, or supersaturated based on the following observations made after adding a small piece of solid solute to the solution. a. The added solute rapidly dissolves. b. The added solute falls to the bottom of the container where it remains without any decrease in size. c. The added solute falls to the bottom of the container where it decreases in size for several hours and thereafter its size remains constant. d. The added solute causes the production of a large amount of solid white crystals.arrow_forwardIn your own words, explain why (a) seawater has a lower freezing point than fresh water. (b) salt is added to the ice in an ice cream maker to freeze the ice cream faster.arrow_forward
