ANS: 1
Sodium ions are the major contributors to maintaining water balance through their effect on se-rum osmolality, nerve impulse transmission, regulation of acid-base balance, and participation in cellular chemical reactions. Pickles are a high-sodium food. The remaining options are good sources of potassium, calcium, and magnesium.
