Attractive Forces and Solution Conductivity

What does the term solubility refer to?

• How well a solvent dissolves in a solute to make a solution.

• How well a solute dissolves in a solvent to make a solution.

• The process of a solution separating into its components.

• The ability of a substance to conduct electricity.

What are the two types of attractive forces that compete during the solution process?

• Solute-solute interactions and solvent-solvent interactions.

• Solute-solute interactions and solvent-solute interactions.

• Solvent-solvent interactions and solvent-solute interactions.

• Ionic interactions and covalent interactions.

In the solution process, which type of attractive force determines whether a solute will dissolve in a solvent?

• The weaker of the two attractive forces.

• The stronger of the two attractive forces.

• Only solute-solute interactions.

• Only solvent-solute interactions.

What device is used in the experiment to test if a solution conducts electricity?

• A voltmeter.

• A light bulb.

• A conductivity tester.

• An ammeter.

Which solution conducted electricity in the experiment?

• Sugar water

• Salt water

• Pure water

• Distilled water

What is the primary reason salt water conducts electricity while sugar water does not?

• Salt water is denser than sugar water.

• Salt dissociates into ions in water, allowing charge flow, while sugar molecules remain intact.

• Sugar molecules are larger than salt ions.

• Salt water has a higher boiling point.

What characterizes an electrolyte solution?

• It is a solution that is highly colored.

• It is an aqueous solution containing dissolved ions.

• It is a solution that is very dense.

• It is a solution that is non-conductive.

What is the key difference between a strong acid and a weak acid when dissolved in water?

• Strong acids are molecular compounds, while weak acids are ionic compounds.

• Strong acids completely ionize in solution, while weak acids incompletely ionize.

• Strong acids are always more concentrated than weak acids.

• Strong acids produce H+ ions, while weak acids produce OH- ions.
