Product Overview
Methyl orange indicator powder is a synthetic azo dye widely used in laboratories for pH testing and titration procedures. This high-purity, laboratory-grade powder provides sharp color transitions between red (pH 4.4), making it ideal for precise acid-base determinations. The fine powder form ensures complete solubility in aqueous solutions, delivering consistent results across experiments. Its stable chemical structure guarantees long shelf life when stored properly in airtight containers away from direct light. The reagent-grade quality meets strict laboratory standards, ensuring accuracy in analytical applications. This indicator works effectively in both educational and research settings where reliable pH detection is critical. The powder form allows for flexible preparation of indicator solutions at various concentrations as required by specific protocols. Its non-hygroscopic nature prevents moisture absorption, maintaining purity over extended storage periods.
FAQs
1. What is the exact pH range where methyl orange changes color?
Methyl orange transitions from red to orange between pH 3.1 and 4.4, with the most noticeable change occurring around pH 3.8.
2. Can this powder be used to prepare indicator solutions for titration?
Yes, the powder readily dissolves in water to create standard indicator solutions for volumetric analysis and titration procedures.
3. How should I store this indicator powder for maximum shelf life?
Store in a cool, dry place in the original airtight container, protected from light and moisture to maintain stability.
4. Is this methyl orange suitable for non-aqueous titrations?
While primarily used in aqueous solutions, it can be adapted for some non-aqueous systems with appropriate solvent selection.
5. What alternatives exist if I need a different pH range indicator?
Phenolphthalein (pH 8.3-10) or bromothymol blue (pH 6.0-7.6) serve as common alternatives for different pH ranges.
