Acid Base Balance Complete Test 2024. Concept of Acid-Base Balance -Critical to homeostasis & optimal cellular function -hydrogen ion concentration of body fluids must be kept within narrow range -hydrogen ions determine the relative acidity of body fluids -Acids release hydrogen ions in solution -Bases (or alkalis) accept hydrogen ions into solutions -Hydrogen ion concentration of a solution is measured as its pH normal ranges are 7.35-7.45. (7 is neutral). Normal pH indicates acid b...
