Buffers Henderson-Hasselbalch Equation with One Equation One Unknown

The video tutorial explains the Henderson-Hasselbalch equation, focusing on calculating pH in a buffer system. It discusses the relationship between pKa and pH, especially when the concentrations of conjugate acid and base differ. The tutorial uses lactic acid as an example, illustrating the titration curve and how pH changes with the addition of sodium hydroxide. The video concludes with a calculation showing the pH is higher than the pKa due to the higher concentration of the conjugate base.
