WebTo calculate the pH of a buffer solution, the Henderson-Hasselbach equation is commonly used. This equation can be derived quite simply from the behavior of weak acids (and bases) in solution, which is described by the kinetics of reversible reactions. This very equation is used in our Buffer pH Calculator. Web24 apr. 2024 · Consider a buffer that combines 4.0 M ammonia (NH3) with 1.3 M ammonium ion (NH4+), Consult a pKb table to locate ammonia's pKb, 4.75. Using the buffer equation, determine that pOH = 4.75 + log (1.3/4.0) = 4.75 + log (.325) = 4.75 + (-.488) = 4.6. Remember that pOH = 14 - pH, so pH = 14 -pOH = 14 - 4.6 = 9.4. 00:00 00:00

WebIf the acid dissociation constant of CH3COOH is 1.8*10-5, what is the pH of the buffer solution? As per the Henderson-Hasselbalch equation, pH = pK a + log ( [CH 3 COO – ]/ [CH 3 COOH]) Here, K a = 1.8*10 -5 ⇒ pK a = -log (1.8*10 -5) = 4.7 (approx.). Substituting the values, we get: pH = 4.7 + log (0.6M /0.4M) = 4.7 + log (1.5) = 4.7 + 0.17 = 4.87
