WebNov 8, 2024 · Make a concentrated (50x) stock solution of TAE by weighing out 242 grams of Tris base (FW = 121.14) and dissolving it in approximately 750 milliliters of deionized water. Carefully add 57.1 milliliters of glacial acid and 100 milliliters of 0.5 M EDTA (pH 8.0). After that, adjust the solution to a final volume of 1 liter. WebAboutTranscript. One way to determine the pH of a buffer is by using the Henderson–Hasselbalch equation, which is pH = pKₐ + log ( [A⁻]/ [HA]). In this equation, [HA] and [A⁻] refer to the equilibrium concentrations of the conjugate acid–base pair used to create the buffer solution. When [HA] = [A⁻], the solution pH is equal to the ...
