Answer 1

Answer:

Saponification Value = (A - B) x N x 56.1 W This method is used to determine the total acid content, both free and combined, of tall oil. (Acid number only measures the free acid). The combined acids are primarily esters formed by reaction with the neutral components present in the original tall oil.
