“…Titration with KI03 has been used to determine N2H4, either alone or in the presence of NH2OH (123), arsenic(III) and antimony-(III) in the presence of each other (58), and antimony in arsenic-containing products (59). Amperometric Na2S203 iodometry has been used to study the causes of increased consumption of iodine in the presence of ammonia or amines (250). Following extraction from propellants, nitroglycerin has been determined by reduction with Mohr's salt, addition of KI, and automatic biamperometric titration with Na2S203 (110).…”
