Calcular pH en buffer - ecuación Henderson-Hasselbalch

Here you will find the best explanation on calculating pH in buffer solutions using the Henderson-Hasselbach equation. 0:00 - Introduction 0:38 - Presentation of the exercises 1:01 - Exercise 1: Calculate the pH of a buffer prepared by mixing 0.1 mol of acetic acid with 0.13 mol of sodium acetate in a volume of 1 L. 1:03 - The Henderson-Hasselbalch equation 2:11 - Application of the Henderson-Hasselbalch equation to calculate pH. 4:22 - Exercise 2: Calculate the pH of a buffer prepared by mixing 20 g of acetic acid with 20 g of sodium acetate in a volume of 2 L. Errata: From 0:34, the actual formula for acetic acid should be CH3COOH and for sodium acetate, CH3COONa.
