Product Code : SCL-LC-12278
Potassium Dichromate (SKU SCL-LC-12278), also known as potassium bichromate, is a chromium(VI) oxidising agent for redox chemistry, oxidation-state lessons and dichromate titrations. Because hexavalent chromium is highly hazardous, it belongs in college and senior-school laboratories where trained staff control every step. Colleges, science departments, tender contractors and distributors looking for a laboratory chemicals supplier in India can obtain it from Science Lab Supplies in Ambala, India.
Specifications
The potassium dichromate table separates identity, hazard, storage and paperwork into single rows. In short, this is K2Cr2O7, CAS 7778-50-9, a salt with chromium in the +6 oxidation state and a strong oxidiser that must be kept from organic matter, reducing agents, acids and combustibles; grade, form and pack size come on the quotation.

Applications and Experiments for Potassium Dichromate
The compound can be used to teach oxidising-agent behaviour, electron transfer and dichromate ion chemistry, and in redox titrations where it oxidises iron(II) in acid solution. Trained staff should make up standard solutions in a Volumetric Flask in a ventilated area, and collect every residue as chromium(VI) waste, never poured to drain.
- NCERT Class 12 chemistry (d- and f-block elements): potassium dichromate as an oxidising agent, shown by the teacher.
- B.Sc. volumetric analysis: dichromate titration of iron(II), with the titrant in a Burette for Acids held on a Burette Stand With Fisher Clamp.
- Oxidation-state and colour-change demonstrations in college inorganic practicals.
- Safety training: classification, segregation and disposal of chromium(VI) chemicals.
Standard Scope of Supply
The order supplies one pack of Potassium Dichromate with a batch label, the Safety Data Sheet, shelf-life detail and transport documents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Pack size and grade appear on the quotation.
Packing, MOQ and Lead Time
Ask for a quotation for a single pack or for several college laboratories at once; each quotation lists the packing, delivery time and price for that quantity. Hazardous chemicals are quoted with their transport documents, and matching redox reagents or glassware can be added to the same request.
With an Importer-Exporter Code on record, Science Lab Supplies is able to ship to buyers in Ghana, Ethiopia, Tanzania, Uganda, the UAE and Saudi Arabia. Questions on chromium(VI) paperwork can be raised on the contact page; a redox reagent list fits in the enquiry cart, and college bids are explained on the lab tender page.
Frequently Asked Questions
Is Potassium Dichromate the same as potassium chromate?
No. Potassium dichromate, K2Cr2O7, and potassium chromate are different chromium(VI) salts, and neither is potassium permanganate. Check the formula and CAS number on the label before using either in a method.
How hazardous is this reagent?
It is a hazardous chromium(VI) oxidiser. Use gloves, eye or face protection and ventilation, keep it in restricted storage away from combustibles and reducing agents, and collect all waste for hazardous disposal.
Who supplies the Potassium Dichromate?
Packs are dispatched by Science Lab Supplies, Ambala, India, each with a batch label and Safety Data Sheet, and the quotation names the grade and pack size before anything ships.
Can school students use it?
Only where the institution permits chromium(VI) handling and a trained teacher or technician controls dispensing, demonstration and disposal. It should not be issued for unsupervised student work.
Related Chromium, Iron and Redox Items
These items let a college compare chromium salts in two oxidation states, pair the dichromate with an iron(II) salt and a second oxidiser or ferricyanide for redox work, and protect the eyes of whoever pours. All of them can share one quotation and one set of hazard documents.
