Which of the following is NOT an electrolyte?

Which of the following is NOT an electrolyte?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Chloride

Answer: (C)

Electrolytes are electrically charged particles dissolved in body fluids that conduct electricity and enable essential functions like nerve impulses, muscle contraction, and fluid balance. The common electrolytes include sodium, potassium, chloride, and calcium. Sodium and potassium are the main extracellular positively charged ions; chloride is a major negatively charged ion; calcium is a divalent positive ion important for bones, signaling, and muscle function. Since each of these forms ions in solution, all are electrolytes. So the statement asking which isn’t an electrolyte isn’t applicable here, because none of the options fit that description.
