Product Code : SCL-CA-12678
The Methyl Orange Indicator is an acid–base indicator used for detecting acidic conditions and identifying endpoints in suitable titrations. It is intended for chemistry teachers, laboratory technicians, researchers and supervised students. Its red-to-yellow colour transition provides a clear visual method for studying pH changes and neutralisation reactions.
Product Description
Methyl orange is a synthetic azo-dye indicator with the molecular formula C14H14N3NaO3S. It changes from red in strongly acidic conditions to yellow above its transition interval, with orange shades visible during the change. Its commonly referenced pH transition range is approximately 3.1 to 4.4.
The product may be supplied as a solid indicator or prepared solution, depending on the confirmed specification. Form, concentration, solvent, grade and capacity must therefore be verified before use. Suitable supporting apparatus is available in the chemistry laboratory equipment range and chemical analysis equipment category.
Key Features
- Visible pH response: Changes from red through orange to yellow as acidity decreases.
- Defined transition interval: The commonly cited colour-change range is approximately pH 3.1–4.4.
- Suitable for selected titrations: Provides endpoint indication when its transition range matches the analytical method.
- Educational value: Demonstrates indicator behaviour, neutralisation and pH-dependent molecular change.
- Small-quantity use: Only a controlled amount is normally required for each test.
- Scannable colour result: Contrasting red and yellow colours are easy to observe against a white background.
- Specification-dependent supply: Physical form, strength, solvent and pack size should be confirmed before ordering.

How to Use Methyl Orange
- Read the product label, Safety Data Sheet and approved procedure.
- Wear protective eyewear, suitable gloves and laboratory clothing.
- Place the test solution in clean laboratory glassware.
- Add only the quantity of indicator specified by the method.
- Mix gently and observe the colour against a white background.
- During titration, add titrant slowly near the expected endpoint.
- Record the specified persistent colour change.
- Close the indicator container immediately after use.
Safety note: Avoid ingestion, dust inhalation and direct eye or skin contact. When supplied as a solution, handling requirements depend on its solvent composition; consult the current Safety Data Sheet before use.
Care & Maintenance

Frequently Asked Questions
What is Methyl Orange used for?
Methyl Orange is used as an acid–base indicator in selected titrations and pH demonstrations. Its transition range must match the expected endpoint of the procedure.
What colour does Methyl Orange show?
It is red under strongly acidic conditions, orange through its transition interval and yellow above that interval.
What is the pH range of Methyl Orange?
Its commonly cited transition range is approximately pH 3.1 to 4.4. The exact observed shade can depend on concentration, lighting and sample conditions.
Can Methyl Orange be used for every titration?
No. It is suitable only when its colour-change interval overlaps the steep pH change near the required endpoint.
Can students use Methyl Orange?
Yes, during authorised chemistry practicals under direct supervision. Students should use controlled quantities and the specified protective equipment.
Is this product supplied as powder or solution?
The supplied physical form must be confirmed before ordering. Buyers should also verify concentration, solvent, capacity, grade and shelf life.
