The electrolyte represented by the symbol Cl is:

The electrolyte represented by the symbol Cl is:

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

Answer: (D)

Cl denotes chloride, the chloride ion that serves as an electrolyte in body fluids. Electrolytes are charged particles that conduct electricity in solution, and chloride (Cl−) is the major extracellular anion, helping to maintain osmotic balance and acid-base status. It pairs with sodium to form common salts like NaCl, contributing to fluid balance and stomach acid production. Glucose is a sugar, not an electrolyte. Sodium and potassium are indeed electrolytes, but their symbols are Na+ and K+, not Cl. So the substance represented by Cl is chloride.
