WebBuffers typically consist of an acid-base pair, with the acid and base differing by the presence or absence of a proton (a conjugate acid-base pair). For instance, one of the buffers that maintain the pH of human blood involves carbonic acid (H _2 2 CO _3 3) and its conjugate base, the bicarbonate ion (HCO _3 3 ^- − ).

WebAs carbonic acid dissociates, H+ are buffered by hemoglobin proteins. At the lungs, the reaction sequence is reverse and CO2 diffuses into alveoli for exhalation. What is the protein buffer system? WebA buffer is simply a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffers work by reacting with any added acid or base to control the pH. …
