VWR® Silver Sulphate (≥98.5%), supplied under the AnalaR NORMAPUR® analytical reagent grade, is a high-quality inorganic salt widely used in analytical chemistry, electrochemical studies, and environmental analysis. With a high assay and strict impurity limits, it is suitable for trace-level determinations and regulated laboratory applications.
Silver sulphate is sparingly soluble in water and finds frequent use as a precipitating agent, electrochemical standard, and catalyst in oxidation reactions. Its controlled impurity profile (chloride ≤20 ppm, copper ≤5 ppm, iron ≤10 ppm, lead ≤10 ppm) ensures accuracy and reproducibility in sensitive applications.
Key Features
- High Purity: Assay ≥98.5%.
- Analytical Reagent Grade: AnalaR NORMAPUR® ensures compliance with stringent quality standards.
- Controlled Impurities: Low levels of chloride, copper, iron, and lead.
- Reliable Performance: Tested for water solubility, insoluble matter ≤0.02%.
- Versatile Reagent: Suitable for analytical chemistry, catalysis, and electrochemistry.
Applications
- Analytical Chemistry: Used in gravimetric and argentometric methods.
- Electrochemistry: Component in silver-silver sulphate reference electrodes.
- Environmental Testing: Determination of chloride and halides.
- Catalysis: Oxidation and organic synthesis reactions.
- Academic & Industrial Labs: Standard laboratory reagent for controlled experiments.
