The following data table contains information that represents the results of a lab that was performed to determine the relationship of the solubility of potassium chloride (KCI) at various temperatures. Temperature (°C) Solubility (g/100mL) 10.0 33.3 20.0 35.4 30.0 35.7 40.0 37.4 50.0 42.0 60.0 44.0 70.0 46.0 80.0 49.0 90.0 50.00 Prepare a graph of the data shown in the table above. In the lab, the manipulated variable is the temperature. Draw a straight line of best fit through the data points. If you need to review how to construct a graph, select here. If you constructed the graph on a computer, upload the file using the attachment tool. If you drew the graph on paper, take a picture and upload it using the attachment tool.

. 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?
Some lithium chloride, LiCl, is dissolved in 100 mL of water in one beaker, and some Li2SO4 is dissolved in 100 mL of water in another beaker. Both are at 10 C, and both are saturated solutions; some solid remains undissolved in each beaker. Describe what you would observe as the temperature is raised. The following data are available to you from a handbook of chemistry:
Temperature influences solubility. Does temperature have the same effect on all substances? Justify your answer. (Hint: Consider Le Chateliers principle.)
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.
