Which electrolyte does sodium primarily work with to maintain acid/base balance?

Sodium primarily works with chloride to maintain acid/base balance in the body. Together, they help regulate fluid balance, blood pressure, and pH levels. Chloride, being an anion, often pairs with sodium, which is a cation, to form strong bonds and contribute to various physiological processes. In the context of acid/base balance, the combination of sodium and chloride helps to buffer changes in acidity and alkalinity in the blood, aiding in the body's homeostasis.

The relationship between sodium and chloride is significant in terms of maintaining osmotic pressure and fluid distribution. Sodium's role in the renal system, alongside chloride, is essential for the reabsorption of water and other electrolytes, impacting the overall acid/base equilibrium.
