Figure P11.1 shows a particle-level view of a sealed container partially filled with a solution that has two components: $X$ (blue spheres) and $Y$ (red spheres). Which of the following statements about substances $X$ and $Y$ are true?
a. $X$ is the solvent in this solution.
b. Pure $Y$ is a volatile liquid.
c. If $Y$ were not present, there would be fewer X particles in the gas above the liquid solution.
d. The presence of $Y$ increases the vapor pressure of $X$.

Kidney Dialysis Semipermeable membranes of the sort used in kidney dialysis do not allow large molecules and cells to pass but do allow small ions and water to pass. Figure $P 11.7$ shows such a membrane separating fluids of various compositions.
a. In which direction does the water
flow in each apparatus?
b. In which direction do sodium ions Aow in each apparatus?
c. In which direction do the potassium ions flow in each apparatus?
