Product Code : SCL-LC-12167
Potassium Chromate (SKU SCL-LC-12167) is an inorganic chromate reagent, K2CrO4, for authorised chemistry laboratories carrying out analytical, qualitative and teaching procedures, including the indicator step of chloride titrations. As a hazardous hexavalent chromium compound it is meant for trained users. Colleges, universities, analytical labs and supervised school labs can request it from Science Lab Supplies in Ambala, India, which prepares item-wise quotations for institutions, contractors and distributors.
Specifications
The K2CrO4 specification is broken down row by row below. In short, it is potassium chromate, CAS 7789-00-6, a yellow crystalline chromate salt that is treated as a restricted hazardous chemical because it contains hexavalent chromium. Grade, assay and pack size are given on the quotation and the container label.

Applications and Experiments for Potassium Chromate
Potassium chromate serves as the indicator in Mohr-type titrations, where silver chloride precipitates first and red silver chromate marks the end point. It is also a reagent in inorganic qualitative analysis and in teaching chromate–dichromate chemistry, always inside a controlled laboratory with trained supervision.
- B.Sc. analytical chemistry: chloride by Mohr's method where lab policy permits, with the indicator added from a 60 mL Dropping Bottle and the titrant read on Burettes with Schellbach Stripe.
- Class 12 salt analysis: teacher-supervised confirmatory tests that form yellow chromate precipitates.
- Chromate and dichromate equilibrium demonstrations in college chemistry.
- Training in handling, labelling and disposing of hazardous inorganic reagents, wearing single-use Gloves Protective made against acids, bases and organic liquids.
Handle it only with chemical-resistant gloves, eye protection and exposure controls, avoid raising dust, and collect all residues as chromium-containing hazardous waste, never into drains. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Standard Scope of Supply
The reagent comes in a sealed container with a label showing batch, grade and hazard information, accompanied by its Safety Data Sheet and packed in a tamper-sealed outer pack with export documentation. The pack size appears on the quotation, and burettes, flasks or other titration items can be quoted alongside.
Packing, MOQ and Lead Time
A quotation can be made for a single container or for a stockroom quantity, and it sets out the pack size, packing, delivery time and price. If you are building a titration apparatus set or a salt-analysis kit, the other reagents and glassware can be quoted on the same sheet.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE, subject to the carriage rules for hazardous chemicals. For a chromate quotation, note the quantity on the contact page or in the enquiry cart; tender documents are handled through the lab tender page.
Frequently Asked Questions
What is potassium chromate used for?
It is the indicator in Mohr-type chloride titrations, a reagent in qualitative inorganic analysis, and a teaching chemical for chromate chemistry in authorised laboratories with trained staff.
Is potassium chromate hazardous?
Yes. It is a hexavalent chromium compound and must be handled with gloves, eye protection, controlled storage and hazardous-waste disposal, by trained staff or under their direct supervision.
Can it be used in schools?
Only in authorised school laboratories with trained supervision, proper chemical storage and arrangements for hazardous waste. It is not for unsupervised student handling.
Who supplies Potassium Chromate?
Potassium Chromate is quoted by Science Lab Supplies of Ambala, India, directly to colleges, analytical laboratories, authorised schools, contractors and distributors, with the batch pack size and grade written on each quotation.
