WebMakes corrections for the temperature at which the buffer will be used; Makes Debye-Huckel corrections for the effect of ionic strength on pKa; Describes two ways (titration or by accurate weight) for preparation of the recipe; Choose the buffer species you want to use, and enter parameters for volume, pH, and concentration of buffer species. WebBy the calculations that we've just done, we've seen that the effective pH range of a buffer is plus or minus one of the pKa value of the weak acid. Let's use these concepts of an effective pH range to choose a buffer solution. Let's say we want to buffer a solution at a pH of 9.00 at 25 degrees Celsius.
