Which two ions are most important in acid-base balance in the body?

Question

Quizplus · Accepted Answer

The two ions most important in acid-base balance in the body are bicarbonate ions (HCO₃) and hydrogen ions (H+). Bicarbonate acts as a buffer to neutralize excess acid in the body, while hydrogen ions are the main component of acids in the body. Chloride (Cl-) and sodium (Na+) also play a role in acid-base balance, but they are not as directly involved as bicarbonate and hydrogen ions. Calcium ions (Ca++) are primarily involved in muscle and nerve function, and potassium ions (K+) are involved in various cellular processes, but neither are as crucial for acid-base balance as bicarbonate and hydrogen ions.
