Chromium Sulfate (Product Code: SCI-705/311) is an analytical reagent grade chromium(III) salt used to study transition-metal colours, amphoteric hydroxides and chromium oxidation states in college and senior school chemistry laboratories. It comes as a 100 g pack with its MSDS and gives teachers a trivalent chromium source for demonstrations that do not start from chromate or dichromate. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, whose laboratory chemicals range covers transition-metal salts like this one.

Chromium(III) sulfate solutions are violet or green depending on what surrounds the chromium ion, and gently heating a violet solution turns it green as sulfate joins the complex — a simple way to introduce complex ions and ligand exchange. Adding sodium hydroxide gives a grey-green precipitate of chromium(III) hydroxide that dissolves in excess alkali to a green solution, the standard demonstration of an amphoteric hydroxide.
Warming that alkaline solution with hydrogen peroxide oxidises chromium(III) to yellow chromate, showing the change from the +3 to the +6 oxidation state; the product is a chromium(VI) compound and must be collected as hazardous waste. In industry, basic chromium sulfate is the tanning agent behind chrome-tanned leather, a useful applied-chemistry example. Wear gloves, avoid raising dust and keep all chromium residues out of the sink.
ScienceLab is how Jain Scientific Equipments Private Limited trades, and the company supplies Chromium Sulfate from Ambala in 100 g packs with the MSDS for inorganic chemistry teaching. Colleges and schools often buy transition-metal salts as a set, so it can be quoted with nickel, cobalt, copper and iron salts for institutions, dealers and importers in India and international markets.

Why is Chromium Sulfate solution green or violet?
Chromium Sulfate solution is violet when only water molecules surround the chromium(III) ion and turns green when sulfate ions join the complex, which happens on heating. Chromium Sulfate SCI-705/311 lets students watch this ligand change, a clear introduction to complex ions.
How does Chromium Sulfate show amphoteric behaviour?
Add dilute sodium hydroxide to a Chromium Sulfate solution and a grey-green chromium(III) hydroxide precipitate forms; add more alkali and it dissolves to a green solution. Because the hydroxide also dissolves in acid, Chromium Sulfate SCI-705/311 is a standard amphoteric-hydroxide demonstration.
Is Chromium Sulfate hazardous?
Chromium Sulfate is a chromium(III) compound, less hazardous than chromium(VI) compounds such as dichromates, but it should still be handled with gloves and without raising dust. Follow the MSDS supplied with the 100 g SCI-705/311 pack and collect chromium residues for proper disposal.
How should Chromium Sulfate be stored?
Keep Chromium Sulfate SCI-705/311 in its closed container in a cool, dry place, away from strong oxidising agents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Who supplies Chromium Sulfate SCI-705/311?
Chromium Sulfate SCI-705/311 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources this analytical reagent and provides it with its MSDS to colleges, schools, dealers and importers in India and international markets.
What does a Chromium Sulfate quotation need?
A Chromium Sulfate quotation needs the product code SCI-705/311, how many 100 g packs you want, the delivery location and any other transition-metal salts for the same course. Share these through the contact page or the enquiry cart to receive a quotation.
