Question

what happens to the concentration of H positive in the blood during acidosis and how are they buffered

Answer 1

During acidosis the concentration of H⁺ increases by several time which makes the blood acidic by decreasing the pH of the blood. During acidosis the concentration of CO₂ increases inside the cells, which combines with water to form H₂CO₃ (carbonic acid) which gets dissociate into H⁺ (taken by haemoglobin) and HCO₃^-(bicarbonate). Bicarbonate is secreted outside the cells in exchange of chloride where in the blood it accept the excess of H⁺ to increases the pH and causes metabolic alkalosis.
