WebNov 7, 2024 · The value of r is determined by the p Ka of the acid form of the buffer pair and target pH we set. Thus, the two equations we set up here are 10 pH – pKa = b / a = r N = a + b Solving this pair of equations is fundamental to any buffer preparation calculation, as is illustrated in the example problems . Practical aspects of buffers WebTherefore, the pH of the buffer solution is equal to the pKa value of the weak acid plus one. This value for the pH represents the upper limit of the effective pH range. Next, let's calculate the pH of the buffer solution when the concentration of weak acid is 10 times the concentration of the conjugate base.
