Product Overview
This 0.1 mol/L copper sulphate solution is a pre-standardized analytical reagent designed for laboratory applications requiring precise copper ion concentration. Formulated using high-purity copper sulphate pentahydrate (CuSO₄·5H₂O) dissolved in deionized water, it eliminates the need for in-house preparation while ensuring batch-to-batch consistency. The solution maintains a stable blue hue indicative of Cu²⁺ ions, with pH balanced to prevent precipitation or hydrolysis. Its analytical grade certification guarantees minimal impurities (<0.001% heavy metals), making it suitable for sensitive techniques like complexometric titrations with EDTA or electrochemical studies. The 1-liter packaging in HDPE bottles with tamper-evident seals preserves integrity during storage and handling. Each batch undergoes spectrophotometric verification at 810nm to confirm molar concentration, with certificates of analysis provided for traceability. The solution’s low particulate count (0.5µm) ensures compatibility with filtration-based protocols. Unlike solid copper sulphate, this liquid form offers immediate usability without dissolution delays, while the standardized concentration simplifies volumetric calculations in experimental setups.
FAQs
1. What is the shelf life of this 0.1M copper sulphate solution when stored properly?
When stored in the original tightly sealed HDPE bottle at 15-25°C away from direct sunlight, the solution remains stable for 24 months from the date of manufacture. Avoid freezing as it may alter the concentration due to potential salt precipitation.
2. Can this solution be used directly for copper electroplating applications?
The 0.1M concentration is suitable for small-scale electroplating experiments, but you may need to adjust the pH (typically to 1-2 using sulfuric acid) and add brightening agents depending on your specific plating requirements. For industrial electroplating, higher concentrations are generally preferred.
3. How does this compare to preparing copper sulphate solution in-house from solid CuSO₄·5H₂O?
This pre-made solution offers three key advantages: guaranteed molar accuracy (±0.5%), elimination of weighing errors, and time savings by bypassing the dissolution and standardization steps. In-house preparation risks incomplete dissolution (especially in cold conditions) and potential contamination from impure water or glassware.
4. What precautions should be taken when handling this solution?
While not classified as highly hazardous, the solution is mildly irritating to skin and eyes. Always wear nitrile gloves and safety goggles when handling. In case of contact, rinse immediately with plenty of water. The solution is also toxic to aquatic life, so avoid disposal into drains or water bodies.
5. Is this solution compatible with automatic titrators or robotic liquid handling systems?
Yes, the solution’s low viscosity (1.02 cP at 20°C) and absence of particulate matter make it compatible with most automated systems. However, we recommend verifying compatibility with your specific instrument’s tubing materials, as prolonged contact with certain plastics may cause leaching.
