WebThe typical pH range for reversed-phase separations on silica-based columns is between 2 to 8. The buffer must have a pKa close to the desired pH, since buffers control pH best at their pKa. As a rule of thumb, it is ideal to choose a buffer with a pKa value <2 units of the desired mobile phase pH. WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.

Here [H+][OH–] = [H+]2 or [H+] = 1 × 10-14M2 and [H+] = [OH–] = 10-7M Because the total concentration of H+and OH–is constant, an increase in one ion is compensated by a decrease in the concentration of other ion. This forms the basis for the pH scale. grass fed round steak
