Which compound is an electrolyte?

Explanation:
Electrolytes produce ions in water, which allows the solution to conduct electricity. Glucose and sucrose stay as neutral molecules and do not dissociate, so they are non-electrolytes. Ethanol also remains largely as molecules and does not ionize, so it is a non-electrolyte. Acetic acid, however, partially ionizes in water: CH3COOH + H2O ⇌ CH3COO- + H3O+. The ions formed enable conductivity, making acetic acid an electrolyte.
