Verified step by step guidance1
Understand the definition of an electrolyte: Electrolytes are substances that dissociate into ions when dissolved in water, conducting electricity.
Identify the substances listed: sodium, chloride, glucose, and potassium.
Determine which of these substances dissociate into ions in solution: Sodium (Na+) and chloride (Cl-) are ions, and potassium (K+) is also an ion.
Recognize that glucose is a molecule that does not dissociate into ions in solution, thus it does not conduct electricity.
Conclude that glucose is the substance that is NOT an electrolyte, as it does not form ions in solution.
