Exercises and Problems 234-e 8-86 Assume that you have identical volumes of two liquids; the first is 0.3 M glucose solution and the second is 0.1 M glucose solution. Based on the diagrams in Problem 8-85, where red is the 0.3 M glucose and blue is the 0.1 M glucose, which one of the diagrams best represents the two liquids after they have stood uncovered for a few days and some evaporation of liquid has occurred? 007 What is the...

7. If 23:0M solution of glucose (CHO), a 2.0 M solution of Na,$0, and a 1.0 M solution of (NH4)3PO4, is made, which solution will have the lowest vapor pressure, highest boiling point, and lowest freezing point? In Part 1 of this experiment you will determine the freezing point of benzophenone. Ben- zophenone is a solid at room temperature and is completely dissolved at 50°C. By letting the liquid cool and measuring the temperature as a function of time, the...
