Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

The blue line on the diagram illustrates the effect of using fractional distillation to separate a mixture of hexane (C6H14) and heptane (C7H16). If one starts a fractional distillation with a 0.20 mole fraction of hexane, what is the approximate mole fraction of hexane in the vapor phase after two evaporation condensation cycles?

In regards to freezing point depression: The original experiment calls for 3 grams lauric acid and .4 g benzoic acid to be melted and then observed to crystalize to demonstrate freezing point depression. A student misreads the directions and adds 4.0 g of benzoic acid instead of 0.4 g. What do you expect to happen? Would the experiment still be valid? Explain your reasoning. I think that since the amount of lauric acid (3g) doesnt change that the solution may be too oversaturated with benzoic acid. I'm not sure if this would still demonstrate freezing point depression since it is a colligative property based on amount of solute....
A mixture of solvents contains 5 mol of solvent A and 10 mol of solvent B. Partial molar volume of solvent A is 100 mL/mol in this mixture and partial volume of B is 80 mL/mol.

We obtain the value of the ebulloscopic increase of a solution with respect to the solvent. The measured boiling point for the solvent, with its absolute error, is 177±2°C; and that of the solution, 183±4°C. Indicate the statement that is correct.(A). From this experiment it is not possible to give a significant value for the ebulloscopic increase.(B). The ebulloscopic increase is 6±4°C.(C). The relative error in the measurement of the boiling temperature of the solution is twice the relative error in the measurement of the boiling temperature of the pure solvent.(D). The relative error of ebulloscopic magnification is, in round numbers, 2%.
