pH 3.0 (red) - pH 4.4 (yellow) Ready-to-use reagent. Prepared with ACS reagent grade Methyl Orange and high purity water. Suitable for laboratory use.
Product Overview
Methyl Orange is a well-known azo dye used as a pH indicator in acid-base titrations, particularly effective for detecting the endpoint of strong acid–weak base reactions. It exhibits a sharp color change from red to yellow over the pH range of 3.0 to 4.4, providing clear visual feedback in analytical procedures.
Due to its vivid transition and high sensitivity in acidic environments, Methyl Orange is widely used in laboratories, teaching settings, and water analysis applications. It is available in both powder and ready-to-use aqueous solution formats.
Key Features:
- pH transition range: 3.0 (red) to 4.4 (yellow)
- Distinct, easily visible color change for titration endpoints
- Ideal for strong acid–weak base titrations
- Available as a powder or in pre-mixed solution
- Stable and reproducible under standard lab conditions
Applications:
- Acid-base titrations in analytical chemistry
- Water and wastewater testing
- Laboratory instruction and educational demonstrations
- pH monitoring in acidic chemical processes
- Routine quality control testing in industrial settings
Methyl Orange is a reliable and easy-to-use indicator, offering strong visual contrast and dependable results in acid-base analysis across a wide range of laboratory environments.
