Conductivity of Sodium Chloride Solution

Medium General Chemistry Solution Chemistry

In an experiment, a chemist dissolves 10 grams of sodium chloride (NaCl) in enough water to make 250 mL of solution. The chemist observes the increase in conductivity of the solution due to the presence of free ions.

Based on the properties of ionic compounds in aqueous solutions, which of the following statements correctly describes the behavior of the sodium chloride solution?

The solution will exhibit no conductivity because NaCl is a solid at room temperature.

The solution will exhibit strong conductivity because NaCl dissociates into Na<sup>+</sup> and Cl<sup>-</sup> ions.

The solution will exhibit weak conductivity because NaCl does not completely dissociate in water.

The solution will not conduct electricity as the water molecules hinder ion movement.
