The solubility of benzoic acid (HC7H5O2), is 0.34 g/100 mL in water at 25C and is 10.0 g/100 mL in benzene (C6H6) at 25C. Rationalize this solubility behavior. (Hint: Benzoic acid forms a dimer in benzene.) Would benzoic acid be more or less soluble in a 0.1-M NaOH solution than it is in water? Explain.
Using Figure 3.1, determine a. the number of grams of CuSO45H2O that will dissolve in 100g of H2O at 100C. gCuSO45H2O b. the number of grams of water required to dissolve 4.0g of CuSO45H2O at 100C. Hint: your answer to Problem 1a gives you the needed conversion factor for g CuSO45H2O to gH2O. gH2O c. the number of grams of water required to dissolve 18gKNO3 at 100C. gH2O d. the number of grams of water required to dissolve a mixture containing 18gKNO3 and 4.0g CuSO45H2O, assuming that the solubility of one substance is not affected by the presence of another. gH2O
Sketch a qualitative graph of the pressure versus time for water vapor above a sample of pure water and a sugar solution, as the liquids evaporate to half their original volume.
If a volatile solute is added to a volatile solvent, both substances contribute to the vapor pressure over the solution. Assuming an ideal solution, the vapor pressure of each is given by Raoults law, and the total vapor pressure is the sum of the vapor pressures for each component. A solution, assumed to be ideal, is made from 1.0 mol of toluene (C6H5CH3) and 2.0 mol of benzene (C6H6). The vapor pressures of the pure solvents are 22 mm Hg and 75 mm Hg, respectively, at 20 C. What is the total vapor pressure of the mixture? What is the mole fraction of each component in the liquid and in the vapor?
What is the microscopic explanation for the macroscopic behaviour illustrated in Figure 11.15?
Air contains 78% nitrogen. At 25C, Henry's law constant for nitrogen is 6.8104M/atm, while at 37C, it is 6.2104M/atm. (a) How many milligrams of the nitrogen in the air will dissolve in 3.0 L of water at 25C? The air in the head space above the water has a pressure of 1.38 atm. (b) How many milligrams of the nitrogen in the air will dissolve in 3.0 L of water at 37C? The air in the head space above the water has a pressure of 1.38 atm. (c) How much more nitrogen is dissolved at the lower temperature in mass percent?
