Nitrogen Determination by Kjeldahl - Boric Acid Method Formula
Equation for calculate nitrogen determination by kjeldahl - boric acid method is,
% Nitrogen = [(ml standard acid - ml blank) x N of acid x 1.4007] ÷ weight of sample in grams
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
