Question

Which of the following (a-d) is TRUE regarding solid NaCl dissolving in water The attraction of the water to the ions in NaCl is through dipole-dipole IFs. Water is considered the solute and NaCl the solvent. The partially positive oxygen in water is attracted to the chloride ion. d. The process of separating the sodium ions from the chloride ions is endothermic. All of these statements are true. polar For the following solution, describe the deviation with respect to Raoult's Law: water (H30) and hydrogen peroxide (H2O2). relative ideal b. positive deviation negative deviation d. more information needed e. none of these Which of the following is FALSE regarding the properties of a solution as compared to the pure solvent? a) The solution will have a higher boiling point b) The solution will have a lower freezing point. c) The vapor pressure over the solution is greater than that over the pure solvent. d) The osmotic pressure will increase as the molarity of the solution increases. e) All of these are true. 4. Which of the following solutions would have the lowest freezing point? b) 0.1 M NaBr, sodium bromide 0.1 M CaCl2, calcium chloride 0.1 MK3PO4, potassium phosphate 0.1 M C6H12O6, glucose They all have the same freezing point e)
