Ions are electrically charged particles that are formed when certain compounds are dissolved in water. These solutions will conduct electricity. The Swedish scientist Svante Arrhenius coined the term ion (which means wanderer) to explain why solutions of electrolytes will conduct an electric current. When an electrolyte forms into a solution, it dissolves or dissociates into ions, a process called ionization. If a substance does not ionize, it will not conduct an electric current. Electrolytes include most acids, bases, and salts. Some conductors include hydrogen and sodium chloride, copper sulfate, and potassium nitrate. Substances that are not electrolytes include distilled water, sugar water, and most organic compounds. Which of the following is a nonelectrolyte?

You didn't list any choices.

Some of your statements apply to solutions but are not true in general. Ions do not have to be dissolved in water. They can also exist in gaseous form. Metals conduct electricity without being ionized,

To determine which of the following substances is a nonelectrolyte, we need to understand that nonelectrolytes do not ionize or dissociate into ions when dissolved in water. This means they do not conduct electricity.

The substances mentioned are:
1. Distilled water
2. Sugar water
3. Most organic compounds

Of these, the first and second substances, distilled water and sugar water, do not contain ions and therefore do not conduct electricity. Distilled water is pure water, which does not dissociate into ions and remains as H2O molecules in solution. Sugar water is a solution where sugar molecules dissolve but do not dissociate into ions.

Therefore, the nonelectrolyte among the given substances is sugar water.
