What is the effect of increasing the concentration of a nonvolatile solute on boiling point, melting point, osmotic pressure, and vapor pressure? Match the words in the left column to the appropriate Dlanks in the sentences on the right. The melting point of a solution containing a nonvolatile solute is than the melting point of the pure solvent, so the melting point as the concentration of the nonvolatile solute increases. The boiling point of a solution containing a nonvolatile solute is than the boiling point of the pure solvent, so the boiling point as the concentration of the nonvolatile solute increases. The osmotic pressure of a solution is directly proportional to the molarity of a solution , so the asmotic pressure as the concentration of the nonvolatile solute increases. The vapor pressure of the solution is than the vapor pressure of the pure solvent, so the vapor pressure as the concentration of the nonvolatile solufe increases
