Product Overview
This 0.1M (0.1N) copper sulphate standardized solution is a high-precision reagent designed for accurate titrimetric applications in analytical laboratories. The solution is meticulously prepared and standardized against NIST-traceable reference materials, ensuring reliable and reproducible results in redox titrations and volumetric analysis. The copper (II) sulphate concentration is maintained at 0.1 molar (0.1 normal), providing consistent stoichiometric reactions for quantitative determinations. The solution is free from impurities that could interfere with titration endpoints, making it suitable for sensitive analytical procedures. Packaged in a high-density polyethylene (HDPE) bottle, the solution remains stable under recommended storage conditions, minimizing degradation over time. The standardized nature of this solution eliminates the need for in-house preparation and titration, saving valuable lab time while maintaining compliance with international analytical standards. Its uniform composition and documented traceability make it an essential reagent for quality control, research, and educational laboratories requiring precise copper ion concentrations.
FAQs
1. What is the shelf life of this copper sulphate standardized solution?
The solution remains stable for 12 months from the date of manufacture when stored in its original, tightly sealed container at room temperature, away from direct sunlight and moisture. Regular recalibration is recommended if used beyond this period.
2. Can this solution be used for iodometric titrations?
Yes, this 0.1M copper sulphate solution is suitable for iodometric titrations where copper (II) acts as an oxidizing agent, provided the reaction conditions and indicators are appropriately selected for the specific analyte being determined.
3. Is this solution compatible with automatic titrators?
The solution is fully compatible with most automatic titrators, as its standardized concentration and low impurity profile ensure consistent performance in automated systems. However, always verify electrode compatibility with copper-based solutions.
4. What precautions should be taken while handling this solution?
While not highly hazardous, standard lab precautions should be followed: wear nitrile gloves, safety goggles, and a lab coat. Avoid skin contact, as copper sulphate can cause irritation. In case of spillage, neutralize with sodium bicarbonate and clean with plenty of water.
5. How is the concentration of this solution verified?
The concentration is verified through potentiometric titration against a primary standard (e.g., arsenic trioxide or sodium thiosulphate) and cross-checked with NIST-traceable reference materials, ensuring accuracy within ±0.1% of the stated molarity.
