Product Name – Chrome Azurol S Quantity/Pack Size – 10 g, 25 g Form – Powder Grade – Laboratory Grade Application – Complexometric titrations, metal ion detection
Product Overview
Chrome Azurol S is a synthetic azo dye widely used as a metallochromic indicator in complexometric titrations, particularly for detecting metal ions like aluminum, calcium, and magnesium. This high-purity, laboratory-grade powder delivers sharp color transitions from blue to pink, ensuring precise endpoint detection in analytical procedures. Its stability under standard lab conditions and compatibility with EDTA titrations make it a reliable choice for quantitative analysis. The reagent is insoluble in water but soluble in organic solvents, allowing versatile preparation for various assay protocols. With minimal interference from common ions, Chrome Azurol S provides consistent performance in both research and routine testing environments. Its non-toxic nature and long shelf life when stored properly further enhance its practicality for laboratory applications.
FAQs
1. What is the solubility of Chrome Azurol S in water?
Chrome Azurol S is sparingly soluble in water but dissolves well in ethanol and other organic solvents for preparation.
2. Can this indicator be used for calcium titration?
Yes, it is effective for calcium titrations when paired with EDTA, showing a distinct color change at the endpoint.
3. How should Chrome Azurol S be stored for long-term use?
Store in a tightly sealed container, protected from light and moisture, at room temperature to maintain stability.
4. Is this reagent compatible with automatic titrators?
The powder form requires dissolution first, but the prepared solution works well in automated titration systems.
5. What alternatives exist for aluminum ion detection?
Eriochrome Cyanine R or Xylenol Orange can serve as alternatives, though color change mechanisms differ.
