What is the difference between a solute and a solvent?

• A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.

• A solute is the substance that does the dissolving, while a solvent is the substance that is dissolved.

• A solute and a solvent are the same thing.

• A solute is always a liquid, while a solvent is always a solid.

How is concentration defined in a solution?

• The amount of solute per unit volume of solution

• The amount of solvent per unit volume of solution

• The total volume of the solution

• The total mass of the solution

What distinguishes a diluted solution from a concentrated solution?

• The amount of solute present in the solution

• The color of the solution

• The temperature of the solution

• The pH level of the solution

What does conductivity measure in a solution and how is it related to ions?

• Conductivity measures the ability of a solution to conduct electricity, which is directly related to the presence of ions.

• Conductivity measures the temperature of a solution, which is indirectly related to the presence of ions.

• Conductivity measures the pH level of a solution, which is not related to the presence of ions.

• Conductivity measures the color of a solution, which is directly related to the presence of ions.

How does the concentration of ionic compounds in a solution affect its conductivity?

• Increases conductivity

• Decreases conductivity

• No effect on conductivity

• Varies unpredictably

Besides ionic compounds, what other types of solutions can conduct electricity?

• Covalent compounds

• Metallic solutions

• Aqueous solutions of acids and bases

• Non-polar solvents
