About This Product
Zinc sulphate solutions are prepared for practicals on zinc salts, ions and solubility, and for electrochemistry demonstrations where the method specifies zinc sulphate. Since the anhydrous salt and the heptahydrate differ in molecular weight, the form on the label is identified before weighing. Goggles, gloves and a lab coat are worn, the reagent is kept dry, and dust is not inhaled.
Frequently Asked Questions
Q1. Which molecular weight is used for calculations?
