WebJun 13, 2024 · If we take 0.36 mol of acetate ion and 1 mol of acetic acid, we can calculate the pH with the Henderson-Hasselbalch solution. CH 3 COOH + ⇌ H + +CH 3 COO – pH=pK a +log⁡([Base]/[Acid] ) pH=4.74+log⁡(0.36/1) pH=4.3. Most buffer solutions should be prepared, so the concentration of the weak acid/base and its conjugate base/acid is close ... WebpH = pKa + log10 ( [A–]/ [HA]) Where [A –] denotes the molar concentration of the conjugate base (of the acid) and [HA] denotes the molar concentration of the weak acid. Therefore, the Henderson-Hasselbalch equation can also be written as: An equation that could calculate the pH value of a given buffer solution was first derived by the ...
