Chapter 21.3, Problem 17R

To determine

To Explain:The types of solute particles that are present in the water solution of electrolytes and nonelectrolytes.

Answer to Problem 17R

If the electrolyte's molecules are dissolved in the water, then the solution conducts electricity,for example, salts and when the nonelectrolytes are dissolved in water, they do not conduct electricity in water,for example, sugar in water.

Explanation of Solution

Introduction:

The molecules that produce ions after dissolving in the water are known as electrolytes.

The molecules that do not produce ions after dissolving in the water are known as nonelectrolytes.

When the electrolyte's molecules are dissolved in the water then the solution conducts electricity. This conduction of electricity is due to the ions present in the solution that is produced by electrolytes. So electrolytes conduct electricity when dissolved in water, e.g sodium chloride.

On the other hand, when the nonelectrolytes are dissolved in water, they do not conduct electricity in the water.

The nonelectrolytes do not produce the ions in water so due to the absence of ions, the solution does not conduct electricity, e.g fats and sugar in water.
