Product Code : SCL-LC-12278
Potassium Dichromate (SKU SCL-LC-12278), also known as potassium bichromate, is a chromium(VI) oxidising agent used 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. Science Lab Supplies sources and supplies it from Ambala, India, for colleges, science departments, tender contractors and distributors needing a laboratory chemicals supplier in India.
Specifications
This reagent is K2Cr2O7, a salt containing chromium in the +6 oxidation state. It is a strong oxidiser and must be kept apart from organic matter, reducing agents, acids and combustibles. Grade, assay, physical form and pack size are confirmed on the quotation and batch label rather than assumed here.

Applications and Experiments for Potassium Dichromate
The compound is used to teach oxidising-agent behaviour, electron transfer and dichromate ion chemistry, and in redox titrations where it oxidises iron(II) under acid conditions. Solutions should be prepared only by trained staff in a ventilated area, and every residue collected as chromium(VI) hazardous waste, never poured to drain.
- NCERT Class 12 chemistry (d- and f-block elements): properties of potassium dichromate as an oxidising agent, shown by the teacher.
- B.Sc. volumetric analysis: dichromate titration of iron(II) solutions.
- Oxidation-state and colour-change demonstrations in college inorganic practicals.
- Laboratory 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 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. Use the contact page for questions, collect items in the enquiry cart, or read the lab tender page before bidding.
Frequently Asked Questions
Is Potassium Dichromate the same as potassium chromate?
No. Potassium dichromate, K2Cr2O7, and potassium chromate are different chromium(VI) salts. Check the formula and CAS number on the label before using either in a method.
How hazardous is this reagent?
It is a toxic 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?
It is supplied by Science Lab Supplies from Ambala, India. The quotation names the grade and pack size, and the Safety Data Sheet travels with the consignment.
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 and Redox Reagents
Colleges ordering dichromate usually also stock other chromium compounds and an iron(II) salt for redox work. The four items below are from the same Lab Chemicals range and can share one quotation, which keeps hazardous-chemical paperwork for a redox practical in a single order.
- Potassium Chromate — a separate hazardous chromate salt for qualitative and analytical procedures.
- Chromic Acid Lab Reagent — restricted chromium(VI) reagent for methods that specify it.
- Chromium Sulphate Lab — chromium(III) salt for comparing oxidation states.
