Determination of Zinc Oxide in Pharmaceutical Preparations by EDTA Titration: A Practical Class for a Quantitative Analysis Course

Zinc oxide is a common additive in food, cosmetics, and medicines. Here, we describe the validation of methods to analyze two pharmaceutical samples containing ZnOtalc powder and dermal ointmentby ethylenediaminetetraacetic acid (EDTA) titration. The methods developed were implemented as a practic...
