Nitrogen Determination by Kjeldahl - Standard Acid Method Formula
Equation for calculate nitrogen determination by kjeldahl - standard acid method is,
% Nitrogen = [((ml standard acid x N of acid) - (ml blank x N of base)) - (ml standard base x N of base) x 1.4007] ÷ WS
Where, N is normality
ml blank is millilitres of base needed to back titrate a reagent blank if standard acid is the receiving solution
SW is weight of sample
