Henderson Hasselbalch Equation |
Phosphate buffers are important in regulating the pH of intracellular fluids at pH values generally between 7.1 and 7.2.
b. Why is a buffer composed of H3PO4 to H2PO4- ineffective in buffering the pH of intracellular fluid?
H3PO4 (aq) ⇌ H2PO4- (aq) + H+ (aq) K a = 7.5 x 10 -3
