orthanilates. The procedure for the estimation is as follows:[21] To the reaction
mixture, a calculated volume of 1 mol dmꢂ3 HCl was added, followed by 10 mL of
pH 5.0 buffer and 10 mL of 1% zinc chloride. The precipitate was filtered, dried at
105–110 ꢀC, and weighed, and the recovery of (C6H7SO3N)2 Zn was found be
around 85%.
