Potassium Chromate
Product Code : SCL-LC-12167
Potassium Chromate (SKU SCL-LC-12167) is an inorganic chromate reagent, K2CrO4, used in authorised chemistry laboratories for analytical, qualitative and teaching procedures, including the indicator step of chloride titrations. It is a hazardous hexavalent chromium compound meant for trained users. Colleges, universities, analytical labs and supervised school labs can obtain it from Science Lab Supplies, which quotes from Ambala, India for institutions, contractors and distributors.
Specifications
The reagent is potassium chromate, formula K2CrO4 and CAS 7789-00-6, a yellow crystalline chromate salt. Because it contains hexavalent chromium it is treated as a restricted hazardous chemical. Grade, assay and pack size are given on the quotation and on the container label for the batch supplied.

Applications and Experiments for Potassium Chromate
Potassium chromate is widely known 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 within a controlled laboratory.
- B.Sc. analytical chemistry: determination of chloride by Mohr's method, where lab policy permits chromate use.
- 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.
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. The pack size appears on the quotation; silver nitrate, burettes and other titration items are separate.
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 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. Reach us through the contact page, collect items in the enquiry cart, or use the lab tender page for institutional tenders.

What is potassium chromate used for?
It is used as the indicator in Mohr-type chloride titrations, as a reagent in qualitative inorganic analysis, and in teaching chromate chemistry in authorised laboratories.
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.
