Product Overview

Sodium thiosulfate 0.01N volumetric solution is a precisely standardized reagent designed for high-accuracy redox titrations in laboratory settings. Formulated as a VOLUSOL® solution, it ensures consistent molarity and reliability without requiring additional preparation. The solution is stabilized to prevent oxidation, maintaining its titer value over extended storage periods when handled correctly. Its clear, colorless appearance allows for easy endpoint detection in titrations, particularly in iodine-based reactions where it acts as a reducing agent. The analytical-grade purity guarantees minimal interference from impurities, making it ideal for quantitative analyses. Packaged in a 1L high-density polyethylene bottle with a tamper-evident seal, the solution is protected from light and atmospheric contamination. The volumetric certification provides traceability to primary standards, eliminating the need for in-house standardization in most applications. This ready-to-use format reduces preparation time while delivering reproducible results across multiple experiments.

FAQs

1. What is the shelf life of this 0.01N sodium thiosulfate solution?

The solution remains stable for 12 months from the date of manufacture when stored unopened in its original container at 15-25°C. Once opened, use within 6 months for optimal accuracy.

2. Can this solution be used directly without further dilution?

Yes, this is a ready-to-use 0.01N volumetric solution that requires no additional dilution for standard titration procedures.

3. How should I verify the titer of this solution before use?

While the solution comes pre-standardized, you can verify the titer by titrating against a primary standard like potassium dichromate using starch indicator for endpoint detection.

4. What precautions should be taken during storage?

Store the bottle tightly sealed in a cool, dark place. Avoid exposure to direct sunlight or temperatures above 30°C, as this may affect the solution’s stability.
