Question
Two beakers are placed in a sealed box at 25 C . One beaker contains 35.0mL of a 0.055M aqueous solution of a nonvolatile nonelectrolyte. The other beaker contains 35.0mL of a 0.04M aqueous solution of NaCl. The water vapor from the two solutions reaches equilibrium. Part A: In which beaker does the solution level rise, and in which one does it fall? answer: The level of the NaCl solution will rise, and the level of the nonelectrolyte solution will fall. Part B: What is the volume in the beaker with the aqueous solution NaCl of when equilibrium is attained, assuming ideal behavior? Part C: What is the volume in the beaker with the aqueous solution of a nonvolatile nonelectrolyte when equilibrium is attained, assuming ideal behavior?Explanation / Answer
a)The level of the NaCl solution will rise, and the level of the nonelectrolyte solution will fall.This is beacuse the nacl solution is valatile and there is aqueous solution so there is ion -effect diuring the equilibrium leading to more of aqueous volume in the equilibrium state b)volume can be calculated by using the henry'law for equilibrium.
