Positively charged electrolytes (cations) have a positive charge due to the presence of extra electrons. Major cations include - Sodium (Na+) Potassium (K+) Magnesium (Mg++) Calcium (Ca++) Negatively charged electrolytes (anions) have a negative charge due to the absence of an electron. Major anions include - Bicarbonate (HCO3-) Chloride (Cl-) Phosphate (H PO4-) The main electrolytes in body fluid - Na+ sodium Cl- chlorine Mg2+ magnesium Ca2+ calcium K+ potassium Hyponatremia Path...
