Potassium Dichromate

Product Code : SCL-LC-12278

The Potassium Dichromate lab chemical is an inorganic chromium(VI) oxidising reagent used for supervised chemistry experiments involving redox reactions, oxidising-agent behaviour, titration demonstrations, and qualitative inorganic chemistry. It is suitable only for trained chemistry laboratories, colleges, science departments, institutional tenders, distributors, and educational procurement buyers.

Product Description

Potassium Dichromate from Science Lab Supplies is intended for controlled educational and laboratory use where a dichromate reagent is required under an approved SOP. The exact grade, assay, pack size, physical form, batch number, shelf life, SDS, COA, and regulatory documents must be confirmed before final publication or quotation.

Potassium dichromate is commonly represented as K₂Cr₂O₇. It contains chromium in the +6 oxidation state and must be handled as a hazardous oxidising chemical. This page describes laboratory-use potassium dichromate only, not consumer, decorative, photographic, or unrestricted-use material.

Key Features

• Chromium(VI) oxidising reagent: suitable for supervised redox chemistry and approved laboratory demonstrations.
• Formula reference: potassium dichromate is represented as K₂Cr₂O₇.
• Redox teaching value: supports lessons on oxidation states, electron transfer, oxidising agents, and titration principles.
• Distinct reagent identity: potassium dichromate should not be confused with potassium chromate or potassium permanganate.
• Strict hazard control: chromium(VI) compounds require SDS-based handling, PPE, ventilation, and restricted access.
• Pack size verification: supplied quantity and container type must be confirmed from the final quotation.
• Documentation-led procurement: SDS, COA, assay, batch number, and transport classification should be verified before use.

How to Use the Potassium Dichromate

1. Read the current SDS, product label, and institutional risk assessment before use.
2. Allow only trained laboratory personnel to dispense or prepare this reagent.
3. Wear suitable PPE, including lab coat, compatible gloves, and eye or face protection.
4. Work in a ventilated area or fume hood if dust, mist, or solution aerosols may be generated.
5. Use only the minimum quantity required by the approved laboratory procedure.
6. Prepare solutions only in labelled, compatible containers using the written SOP.
7. Keep away from organic materials, reducing agents, acids, combustibles, and incompatible chemicals unless an approved method permits the procedure.
8. Collect all residues and contaminated materials as chromium(VI)-containing hazardous waste.

Safety note: Potassium Dichromate must be handled as a hazardous chromium(VI) oxidising reagent. Do not ingest, inhale dust, touch with bare hands, heat unnecessarily, mix casually, or issue for unsupervised student handling.

Care & Maintenance

• Store tightly closed in the original container in a cool, dry, ventilated and restricted chemical-storage area.
• Keep away from combustibles, organic matter, acids, reducing agents, food items, and unlabelled containers.
• Use clean, dry, compatible tools and avoid returning unused material to the original pack.
• Maintain SDS, COA, batch number, grade, pack size, hazard classification, and waste records for audit control.

Frequently Asked Questions

What is Potassium Dichromate used for in a laboratory?

Potassium Dichromate is used as an oxidising reagent for supervised redox chemistry, oxidation-state demonstrations, titration work, and approved inorganic chemistry practicals.

What is the formula of Potassium Dichromate?

The formula of Potassium Dichromate is K₂Cr₂O₇. Its CAS number is 7778-50-9 and its molecular weight is 294.1846 g/mol.

Is Potassium Dichromate hazardous?

Yes. Potassium Dichromate is a hazardous chromium(VI) oxidising chemical. It requires SDS-based handling, PPE, ventilation, restricted access, and controlled hazardous-waste disposal.

Is Potassium Dichromate the same as Potassium Chromate?

No. Potassium dichromate and potassium chromate are different chromium(VI) salts. The label, formula, CAS number, and COA should be checked before procurement or use.

Is it suitable for school chemistry labs?

It is suitable only where the institution permits chromium(VI) chemical handling and trained staff control dispensing, demonstrations, storage, and disposal.

Does it include SDS or COA?

SDS and COA availability must be confirmed for the final supply. These documents should be requested before procurement, storage, classroom use, transport, or disposal planning.
