WebThe conjugate base of a strong acid would be an exceedingly weak base and so it would be severely limited in neutralizing additional acid. Essentially the addition of more acid would lower the pH even more so. The purpose of a buffer is to resist these drastic changes in pH so a strong acid buffer wouldn't really be achieving that.

WebFirstly, the resting blood lactate levels in one study were between 0.6-mM and 1.2-mM per litre. I know this isn’t much compared to what it can rise to – 30 is recorded and I’m sure I’ve read 40 somewhere – during intense anaerobic exercise, but 1.2 is double 0.6. I’ve seen a higher range described too.

WebA buffer is a solution of a weak acid and its conjugate base. In blood, the principle buffer system is the weak acid, carbonic acid (H 2 CO 3) and its conjugate base, bicarbonate (HCO 3 –).
