Nonelectrolyte
Definition and meaning of Nonelectrolyte in chemistry.
A nonelectrolyte is a substance that does not readily ionize when dissolved or melted, meaning its solutions cannot conduct an electric current. These chemical compounds dissolve into neutral molecules rather than separating into charged ions.
In more detail
Most nonelectrolytes are covalently bonded organic compounds, such as sugars and alcohols. When they are added to a solvent like water, the intermolecular forces may break down, but the strong covalent bonds holding the individual molecules together remain completely intact. Because there are no free-moving charged particles dispersed in the resulting solution, electricity cannot flow through the liquid phase.
Key facts
| Field | General Chemistry |
|---|---|
| Example Formula | C12H22O11 (Sucrose) |
| Conductivity | Does not conduct electricity in solution |
Sucrose (table sugar) dissolves readily in water but remains as intact C12H22O11 molecules, making it a classic nonelectrolyte that will not conduct electricity.
Frequently asked questions
How can you test if a substance is a nonelectrolyte?
Dissolve it in pure water and attempt to pass an electric current through it using a conductivity meter; a nonelectrolyte will show zero conductivity.
