Meanwhile for phosphate buffer the pKa value of H_2PO_4- is equal to 72 so that the buffer system is suitable for a pH range of 72-1 or from 62 to 82. If your acid is at a concentration of 15 M you need a concentration of Select Select to create your buffer at the desired pH. Pin On Chemistry Industrially buffer solutions are used in fermentation processes and in setting the correct conditions for dyes used in coloring fabrics. . PH pK a logconj. Basic buffer has a basic pH and is prepared by mixing a weak base and its salt with strong acid. Buffers in the pH. An example of an acidic buffer solution is a mixture of sodium acetate and acetic acid pH 475. The simplest and still an accurate way is to start with the acid form of the buffer component weighed out to the desired molarity and adjust the pH with 1N NaoH. Histidine is the amino acid that function at the physiological PH. Buffer pKa and pH Range Valu...
