Electrolytes vs. Nonelectrolytes

Try to classify the following substances as electrolytes or nonelectrolytes…

Answers to Electrolytes

Ionic Compounds “Dissociate”

Ions tend to stay in solution where they can conduct a current rather than re-forming a solid.

Some covalent compounds IONIZE in solution

Strong acids such as HCl are completely ionized in solution.

Weak acids such as lactic acid usually ionize less than 5% of the time.

Because of the carboxyl group, organic acids are sometimes called “carboxylic acids”.
