6-22 Answer true or false. (a) Water is a good solvent for ionic compounds because water is a polar liquid. (b) Small covalent compounds dissolve in water if they can form hydrogen bonds with water molecules. (c) The solubility of ionic compounds in water generally increases as temperature increases. (d) The solubility of gases in liquids generally increases as temperature increases. (e) Pressure has little effect on the solubility of liquids in liquids. (f) Pressure has a major effect on the solubility of gases in liquids. (g) In general, the greater the pressure of a gas over water, the greater the solubility of the gas in water. (h) Oxygen, O2, is insoluble in water.
Sodium chloride (NaCl) is commonly used to melt ice on roads during the winter. Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water, by calculating the freezing point depression of solutions containing 200. g of each salt in 1.00 kg of water. (An advantage of CaCl2 is that it acts more quickly because it is hygroscopic, that is. it absorbs moisture from the air to give a solution and begin the process. A disadvantage is that this compound is more costly.)
An unknown compound contains only carbon, hydrogen, and oxygen. Combustion analysis of the compound gives mass percents of 31.57% C and 5.30% H. The molar mass is determined by measuring the freezing-point depression of an aqueous solution. A freezing point of 5.20C is recorded for a solution made by dissolving 10.56 g of the compound in 25.0 g water. Determine the empirical formula, molar mass, and molecular formula of the compound. Assume that the compound is a nonelectrolyte.
