📐 Titration Formula

Acid Value = (V - B) × N × 56.1 / W
% FFA = (V - B) × N × F / W

V = Titrant (mL), B = Blank (mL), N = Normality, W = Sample Weight (g), F = Fatty Acid Factor

Select the predominant fatty acid in your sample [citation:1]

Standard sample weight for oil titration [citation:7]

Volume of KOH/NaOH used for the oil sample

Titration without sample (usually 0 or very small) [citation:7]
