Answer #1

The colligative properties of the solutions are the properties that depend only upon the number of solute particles per unit volume present in the solution.

A is not true as the colligative properties are physical properties and not chemical properties.

B is true as the colligative properties depend upon number of solute particles per unit volume of solution.

C is not true as the properties depend upon type of solute but number of solute particles.

D is not true as the properties depend upon concentration of solute.

E is not true as the colligative properties are only vapor pressure lowering , boiling point elevation ,freezing point depression and osmotic pressure.

Colligative properties are those that depend on the number of solute particles. Because electrolytes dissociate into ions, the concentration of particles in the solution is greater than the formula-unit concentration of the solution. For example, if 1 mol of Na2SO4 totally dissociates, 3 mol of ions are produced (2 mol of Na+ ions and 1 molof SO42− ions). Thus, a colligative property such as osmotic pressure will be three times greater for a 1 M Na2SO4 solution than for a...

part a: Colligative properties are only incidentally affected by chemical properties of substances. The most important point is that colligative properties are dependent on the number of free solute particles in solution, not the specific nature of those particles. When dissolving substances, it is important to understand how many particles are released by that substance. One mole of sodium chloride produces two moles of dissolved particles:one mole of Na+(aq) and one mole of Cl-(aq), while one mole of sucrose produces...

For an ideal solution, we discussed in class that the chemical potential is given by: μ=μ_0+RT "ln" (c/c_0 ) where the units of µ written in this form are Joules/mole. The concentration c_0 is a reference concentration, which we will take to be 1 Molar for this problem. Suppose solution 1 with solute concentration of 1 mM (i.e., 1 x 10-3 Molar) is in contact with solution 2 with solute concentration of 0.1 mM (i.e., 1 x 10-4 Molar). If...
