The body's … WebbProper physiological functioning depends on a very tight balance between the concentrations of acids and bases in the blood. Acid-balance balance is measured using the pH scale, as shown in Figure 26.15. A variety of buffering systems permits blood and other bodily fluids to maintain a narrow pH range, even in the face of perturbations.
WebbHCO₃⁻ (aq) + H₂O ⇌ H₃O⁺ (aq) + CO₃²⁻ (aq) CO₂ is always being produced in the cells as part of the normal metabolic process. It enters the blood, where it becomes part of the … WebbAcid is actively excreted into the proximal and distal tubules where it combines with urinary buffers—primarily freely filtered phosphate (HPO 4 −2), creatinine, uric acid, and ammonia—to be transported outside the body.The ammonia buffering system is especially important because other buffers are filtered in fixed concentrations and can …
WebbSo, a hydrofluoric acid buffer would work best in a buffer range of around pH = 3.18. For the weak base ammonia (NH 3), the value of K b is 1.8x10-5, implying that the K a for the dissociation of its conjugate acid, NH 4 +, is K w /K b =10-14 /1.8x10-5 = 5.6x10-10. … Introduction.
