What is the difference between sodium and chloride?

Sodium is the major extracellular fluid (ECF) cation (positively charged ion) and chloride is the major ECF anion (negatively charged ion). Chloride provides electroneutrality, especially in relation to sodium; chloride's transport is generally passive, following the active transport of sodium.
