Determination of Zinc by Complexometric Titration with 2-(5-Chloro-2-Pyridylazo)-5-Diethylaminophenol Indicator
-
ABSTRACT
An accurate and selective method for the determination of zinc by complexometric titration was developed.In the medium of acetic acid-sodium acetate(pH=5.5) and with 2-(5-chloro-2-pyridylazo)-5-diethylaminophenol(5-Cl-DEPAP) as indicator,the amount of zin
