Consider the following solubility versus temperature curve for potassium chloride (KCI). 100 80 KCI 20 40 60 80 100 Temperature (°C) Identify which ONE of the following statements is INCORRECT. a. At equilibrium, solid KCI will be observed in equilibrium with the solution of 60 g KCI per 100 g of water at a temperature of 60 °C. b. At equilibrium, all the KCI will be dissolved in a solution made up from 20 g KCI per 100 g of water at a temperature of 20 °C. OC. The solubility of KCI at 40 °C is 40 g per 100 g of water. d. When a solution of 40 g KCI per 100 g of water at 50 °C is cooled to 20 °C, the solution is supersaturated and therefore is not at equilibrium. e. At equilibrium, no solid is observed after evaporating half the water from a solution of 20 g KCI per 100 g of H₂O at 20 °C. Solubility (g per 100 g H₂O)

Define a saturated solution. Does saturated mean the same thing as saying the solution is concentrated? Explain. Why does a solute dissolve only to a particular extent in water? How does formation of a saturated solution represent an equilibrium?
How are the boiling point and freezing point of water affected by the addition of solute?
What happens if you add a very small amount of solid salt (NaCl) to each beaker described below? Include a statement comparing the amount of solid eventually found in the beaker with the amount you added: a a beaker containing saturated NaCl solution, b a beaker with unsaturated NaCl solution, c a beaker containing supersaturated NaCl solution.

A patient has a “cholesterol count” of 214. Like manyblood-chemistry measurements,this result is measured inunits of milligrams per deciliter (mgdL1). Determine the molar concentration of cholesterol inthis patient’s blood, taking the molar mass of cholesterolto be 386.64gmol1. Estimate the molality of cholesterol in the patient’sblood. If 214 is a typical cholesterol reading among men inthe United States, determine the volume of such bloodrequired to furnish 8.10 g of cholesterol.
Explain why the distinction between solute and solvent is not clear for some solutions.
Maple syrup sap is 3% sugar (sucrose) and 97% water bymass. Maple syrup is produced by heating the sap toevaporate a certain amount of the water. (a) Describe what happens to the composition and boilingpoint of the solution as evaporation takes place. (b) A rule of thumb among maple syrup producers is thatthe finished syrup should boil about 4 C higher than theoriginal sap being boiled. Explain the chemistry behindthis guideline. (c) If the finished product boils 4 C higher than the originalsap, calculate the concentration of sugar in the finalproduct. Assume that sugar is the only solute and theoperation is done at 1 atm pressure.
