WebBuffers used in life science range from 10-4 to 10-10 in their K a values. K a = [ H +][A –]/HA. Where, K a is usually expressed as its negative logarithm. So, pK a is. pK a = -logK a. Concentration. Proportion of current carried by buffer increases and the one carried by sample decreases with the ionic strength of the buffer. Good sought to identify buffering compounds which met several criteria likely to be of value in biological research. 1. pKa: Because most biological reactions take place near-neutral pH between 6 and 8, ideal buffers would have pKa values in this region to provide maximum buffering capacity there. 2. Solubility: For ease in handling and because biological systems are in aqueous systems, good s…
