Product Overview

Zinc Sulphate Heptahydrate 99% AR/ACS (CAS No. 7446-20-0) is hydrated zinc sulphate used as a soluble Zn(II) reagent in conventional analytical chemistry. Zinc ions form well-defined complexes with chelating ligands and participate in precipitation and titrimetric systems, while the heptahydrate composition must be retained when analytical solutions are prepared by mass.

The AR/ACS grade is intended for preparation of analytical zinc solutions, complexometric procedures, metal-ion equilibrium studies and laboratory quality control. Its defined heptahydrate composition supports reproducible preparation of Zn(II) reagent systems used in conventional analytical chemistry.

Typical Applications

• Preparation of non-certified zinc stock and working solutions.
• Complexometric and EDTA-related analytical procedures.
• Metal-ion complexation and masking studies.
• Zinc precipitation and solution-equilibrium investigations.
• Preparation of analytical Zn(II) reagents.
• Laboratory QC and zinc-method development.

Common Synonyms

• Zinc sulfate heptahydrate
• Zinc(II) sulphate heptahydrate
• White vitriol

Storage Conditions

Keep tightly closed and protect from uncontrolled moisture exchange to preserve the heptahydrate composition. Use clean analytical handling to minimise metallic, ionic and particulate contamination.
