Chapter 13: Problem 67

Why is the discussion of the colligative properties of electrolyte solutions more involved than that of nonelectrolyte solutions?

Short Answer

Expert verified
The discussion of the colligative properties of electrolyte solutions is more involved than that of nonelectrolyte solutions because electrolytes dissociate into more particles in solution, thus altering the colligative properties to a greater extent than nonelectrolytes.

Step by step solution

01

Definition of Electrolytes and Non-electrolytes

An electrolyte is a substance that, when dissolved in water, produces a solution that can conduct electricity due to the presence of ions. On the other hand, a non-electrolyte does not dissociate into ions when dissolved in water, so it does not conduct electricity.
02

Explanation of Colligative Properties

Colligative properties are properties of a solution that depend on the number of solute particles in solution, not on the nature or type of solute particles.
03

Dissociation of Electrolytes and Non-electrolytes

When an electrolyte dissolves in a solution, it dissociates into multiple ions. This means that the number of particles in solution increases, which, in turn, affects the colligative properties more significantly. Non-electrolytes do not dissociate into ions, therefore, they do not affect the colligative properties to the same degree.
04

Comparison of Colligative Properties

Because electrolytes produce more particles in solution, they have a greater effect on colligative properties, such as boiling point elevation and freezing point depression, compared to non-electrolytes. This makes discussing the colligative properties of electrolyte solutions more involved than that of nonelectrolyte solutions.

Explain why ethanol \(\left(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\right)\) is not soluble in cyclohexane \(\left(\mathrm{C}_{6} \mathrm{H}_{12}\right) .\)

Briefly describe the solution process at the molecular level. Use the dissolution of a solid in a liquid as an example.

Calculate the percent by mass of the solute in each of these aqueous solutions: (a) \(5.50 \mathrm{~g}\) of \(\mathrm{NaBr}\) in \(78.2 \mathrm{~g}\) of solution, (b) \(31.0 \mathrm{~g}\) of \(\mathrm{KCl}\) in \(152 \mathrm{~g}\) of water, \((\mathrm{c})\) \(4.5 \mathrm{~g}\) of toluene in \(29 \mathrm{~g}\) of benzene.

A very long pipe is capped at one end with a semipermeable membrane. How deep (in meters) must the pipe be immersed into the sea for fresh water to begin to pass through the membrane? Assume the water to be at \(20^{\circ} \mathrm{C}\) and treat it as a \(0.70 \mathrm{M} \mathrm{NaCl}\) solution. The density of seawater is \(1.03 \mathrm{~g} / \mathrm{cm}^{3}\) and the acceleration due to gravity is \(9.81 \mathrm{~m} / \mathrm{s}^{2}\)

Basing your answer on intermolecular force considerations, explain what "like dissolves like" means.
