    The Quantitative Analysis of Acid-Base Titrations: From Lavoisier's Foundations to Modern Analytical Chemistry

    Acid-base titration represents one of the most fundamental and elegant techniques in analytical chemistry, enabling precise quantitative analysis through controlled neutralization reactions.

    Historical Foundations

    Antoine Lavoisier's revolutionary work in the late 18th century established the principles of stoichiometry and mass conservation that underpin modern titration.

    The Henderson-Hasselbalch Equation

    pH = pKa + log([A⁻]/[HA])

    Anatomy of a Titration Curve

    • Initial Region: Before significant base addition, pH is determined by the strong acid concentration.
    • Buffer Region: Henderson-Hasselbalch equation governs pH.
    • Equivalence Point: Moles of acid equal moles of base.

    Modern Applications

    • Pharmaceutical Quality Control: Drug content uniformity and API quantification
    • Environmental Analysis: Water alkalinity measurements (EPA Method 310.1)
    • Food Science: Total acidity in wine and fruit juices
