Methyl Orange Powder (25gm)

Methyl Orange Powder is a synthetic azo dye and acid-base indicator supplied as a sodium sulfonate salt. It undergoes a visible pH-dependent colour change, appearing red in sufficiently acidic solution and yellow at higher pH. The indicator transition range is approximately pH 3.1–4.4, making it appropriate to certain acid-base titrations. This product is listed for laboratory procurement in the pack size shown in its product name; pack size does not alter chemical identity. In educational and institutional settings, this material can support selected experiments, analytical method development or teaching exercises when matched to the procedure and suitable laboratory facilities. Correct reagent identification, applicable safety information and an appropriate method are essential before use. Physical presentation and grade alone do not establish fitness for all analytical or biological methods. Where the product name omits a hydrate form or formulation detail, verify that identity before calculating reagent masses or preparing quantitative solutions. All work should follow institutionally approved laboratory procedures and the specific product safety data sheet.

Frequently Asked Questions About Methyl Orange Powder

What is Methyl Orange Powder used for in laboratories?

Methyl Orange Powder is used in selected institutional laboratory settings. Examples include acid-base titrations with appropriate endpoint ph. and school and college demonstrations of ph indicators. Procedures must be matched to the chemical form, equipment and safety restrictions. It should not be assumed suitable for unrestricted educational use.

What are the formula and CAS number of Methyl Orange Powder?

The molecular formula is C14H14N3NaO3S, and the CAS number is 547-58-0. Some commercial products may have different hydrate forms or formulations. Confirm the manufacturer identification before making quantitative solutions or entering a substance into an institutional chemical inventory.

What key laboratory properties does Methyl Orange Powder have?

It undergoes a visible pH-dependent colour change, appearing red in sufficiently acidic solution and yellow at higher pH. The indicator transition range is approximately pH 3.1–4.4, making it appropriate to certain acid-base titrations. These characteristics can inform experimental planning but do not replace method-specific validation or evaluation of reagent grade and safety.

Is Methyl Orange Powder appropriate for school and research laboratory work?

Use depends on the application, chemical hazards and available engineering controls. Some studies are suitable for supervised educational settings, whereas hazardous mercury or nickel substances require specialist facilities and authorized personnel. Always review the SDS and institutional safety permissions before work.

How should Methyl Orange Powder be stored and handled?

Keep the powder in a tightly sealed, dry, appropriately labelled container away from excessive heat, moisture and strong light. Avoid storage with incompatible reactive chemicals. Prepare and label dilute solutions separately according to laboratory protocols. Consult the current product SDS for any additional requirements. Follow the manufacturer SDS for protective equipment, spill response, incompatible chemicals and waste-disposal requirements.

Storage Conditions for Methyl Orange Powder

Keep the powder in a tightly sealed, dry, appropriately labelled container away from excessive heat, moisture and strong light. Avoid storage with incompatible reactive chemicals. Prepare and label dilute solutions separately according to laboratory protocols. Consult the current product SDS for any additional requirements.

Precautions for Handling Methyl Orange Powder

Consult the SDS and wear safety glasses, gloves and laboratory clothing. Avoid raising dye dust and prevent eye, skin and respiratory exposure. Weigh in a ventilated area and clearly label indicator preparations. Do not use for nonlaboratory purposes. Follow local spill-cleaning and dye-containing waste procedures rather than discharging concentrated residues to drains.
