An impure sample contains 0.74 g of impurities and 4.55 g of benzoic acid. The sample is dissolved in 100 ml of water and heated. The solution is then cooled. How many grams of the impurity will crystallize when the solution has cooled? Include the unit and two decimal places in your answer. The solubilities of the impurity and benzoic acid in cold and hot water are given below. Compound Cold Water solubility Benzoic acid 0.42 g per 100 mL of water 5.79 g per 100 ml of water Impurity Hot Water Solubility 0.61 g per 100 mL of water 4.62 g per 100 mL of water

Every pure substance has a definite and fixed set of physical and chemical properties. A solution is prepared by dissolving one pure substance in another. Is it reasonable to expect that the solution will also have a definite and fixed set of properties that are different from the properties of either component? Explain your answer.
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 saturated sodium chloride solution.
Classify 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.
The specific gravity of a solution of KCl is greater than 1.00. The specific gravity of a solution of NH3 is less than 1.00. Is specific gravity a colligative property? Why, or why not?
Addition of water to concentrated sulfuric acid is dangerous because it generates enough heat to boil the water, causing it to spatter out of the container. For this reason, chemists remember to add acid to water. In a dilution experiment, we calculate the amount of the more concentrated solution that must be measured out. If we place this concentrated solution (Figure 4.7) in the volumetric flask first, then dilute with water, we violate the caution Add acid to water. Describe a safer variation on the method shown in Figure 4.7 that allows the quantitative dilution of concentrated sulfuric acid. Figure 4.7 Preparing a dilute solution from a concentrated solution. (a) Draw the concentrated solution into a pipet to a level just above the calibration mark. (b) Allow the liquid to settle down to the calibration line. Touch the tip of the pipet to the side of the container to remove any extra liquid. (c) Transfer this solution to a volumetric flask. Again touch the pipet to the wall of the flask to ensure complete transfer, but do not blow out the pipet because it is calibrated for a small amount of liquid to remain in the tip. (d) Dilute to the mark with solvent. Frequently, especially with concentrated acids, it is best to have some solvent present in the volumetric flask before you add the concentrated sample.
