Form – Liquid Solution
Grade – AR (Analytical Reagent)
Application – Standardized copper ion source for titration, qualitative analysis
Product Overview
This 1% w/v copper sulphate solution offers a precisely standardized concentration of Cu²⁺ ions in a stable aqueous medium, eliminating the need for manual preparation while maintaining analytical accuracy. The AR grade formulation ensures minimal impurities (≤0.001% heavy metals), with copper content strictly maintained at 99.9% of the labeled concentration through rigorous quality control. The solution utilizes ultra-pure water as the solvent and includes a trace amount of sulfuric acid (0.01N) to prevent hydrolysis and maintain long-term stability. Packaged in amber HDPE bottles with tamper-evident seals, the solution remains protected from photodegradation and contamination. The uniform blue coloration serves as a visual indicator of proper copper ion dispersion, while the pH is buffered to 3.5-4.0 for optimal reagent performance. Each batch undergoes atomic absorption spectroscopy verification to guarantee concentration accuracy within ±0.5% of the specified value, making it particularly suitable for applications requiring reproducible copper ion availability.
FAQs
1. What is the shelf life of this copper sulphate solution when stored properly?
When kept in the original sealed container at 15-25°C away from direct sunlight, the solution maintains its specified concentration for 24 months from the date of manufacture.
2. Can this solution be diluted further for lower concentration requirements?
The solution can be accurately diluted using deionized water, though we recommend preparing fresh dilutions immediately before use to prevent potential copper carbonate formation.
3. What material is the bottle cap made of to prevent contamination?
The bottle features a polypropylene screw cap with an integrated PTFE liner that creates an airtight seal while being chemically inert to the solution.
4. How does the color intensity relate to the copper concentration?
The deep blue color results from the [Cu(H₂O)₆]²⁺ complex, where any noticeable fading would indicate potential copper ion depletion or contamination.
5. What quality documentation accompanies each batch of this solution?
Every shipment includes a certificate of analysis detailing the exact copper concentration, impurity profile, pH value, and batch-specific stability data.
