- Will red blood cells crenate, hemolyze, or remain unaffected when placed in each of the solutions in Problem 8-102?arrow_forwardPure iodine (105 g) is dissolved in 325 g of CCl4 at 65 C. Given that the vapor pressure of CCl4 at this temperature is 531 mm Hg, what is the vapor pressure of the CCl4-I2 solution at 65 C? (Assume that I2 does not contribute to the vapor pressure.)arrow_forwardIndicate the most important type of intermolecular attraction responsible for solvation in each of the following solutions: (a) the solutions in Figure 11.8 (b) methanol, CH3OH, dissolved in ethanol, C2H5OH (c) methane, CH4, dissolved in benzene, C6H6 (d) the polar halocarbon CF2CI2 dissolved in the polar halocarbon CF2CICFCI2 (e) O2(I) in N2(l)arrow_forward
- In a significant experiment performed many years ago, 5.6977 g of cadmium iodide in 44.69 g of water raised the boiling point 0.181 C. What does this suggest about the nature of a solution of CdI2?arrow_forwardWhich ion in each of the following pairs would you expect to be more strongly hydrated? Why? a. Na+ or Mg2+ b. Mg2+ or Be2+ c. Fe2+ or Fe3+ d. F or Br e. Cl or ClO4 f. ClO4 or SO42arrow_forwardArrange the following alkaline-earth-metal iodates in order of increasing solubility in water and explain your reasoning: Ba(IO3)2, Ca(IO3)2, Sr(IO3)2, Mg(IO3)2. Note that IO3 is a large anion.arrow_forward
- Suppose you are presented with a clear solution of sodium thiosulfate, Na2S2O3. How could you determine whether the solution is unsaturated, saturated, or supersaturated?arrow_forwardA 13.0% solution of K2CO3 by mass has a density of 1.09 g/cm3. Calculate the molality of the solution.arrow_forwardWhich of the following salts, Li2SO4 or Cs2SO4, is expected to have the more exothermic enthalpy of hydration?arrow_forward
- When KNO3 is dissolved in water, the resulting solution is significantly colder than the water was originally. (a) Is the dissolution of KNO3 an endothermic or an exothermic process? (b) What conclusions can you draw about the intermolecular attractions involved in the process? (c) Is the resulting solution an ideal solution?arrow_forwardYou have two aqueous solutions separated by a semipermeable membrane. One contains 5.85 g of NaCl dissolved in 100. mL of solution, and the other contains 8.88 g of KNO3 dissolved in 100. mL of solution. In which direction will solvent flow: from the NaCl solution to the KNO3 solution, or from KNO3 to NaCl? Explain briefly.arrow_forwardAn aqueous solution of M2O is prepared by dissolving 10.91 g of the electrolyte in 435 mL of H2O(d=1.00g/mL). The solution freezes at -4.68C. What is M+? (Assume complete dissociation of M2O to M+ and O2-.)arrow_forward
