Sodium Dichromate
Sodium Dichromate (Product Code: SCI-487/208) is an analytical reagent grade dichromate salt used as a strong, water-soluble oxidising agent in organic and inorganic chemistry practicals at colleges and research laboratories. It comes as a 100 g pack with its MSDS and is chosen where a more soluble dichromate than the potassium salt is needed. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India.

What Is Sodium Dichromate Used For?
Sodium dichromate dissolves far more readily in water than potassium dichromate, so it is the usual choice for concentrated oxidising mixtures with sulphuric acid in organic chemistry — for example, oxidising a secondary alcohol such as cyclohexanol to its ketone and then recovering the product with a distillation apparatus. The orange-to-green colour change shows students that the oxidation has taken place.
Unlike the potassium salt, sodium dichromate absorbs moisture from the air, so it is not used as a primary standard for titrations and must be kept tightly sealed. It is a toxic, carcinogenic hexavalent chromium compound: weigh it inside a fume cupboard, wear gloves and eye protection, and keep it apart from organic solvents and reducing agents.
Supplier
Jain Scientific Equipments Private Limited operates under the ScienceLab name and supplies Sodium Dichromate as part of an oxidiser range for college and research chemistry. Tender and institutional buyers can register the supplying company as a vendor using its CIN U29309HR2020PTC087597 and GSTIN 06AAECJ8618A1ZT. Based in Ambala, Haryana, it serves India and international markets; see the ScienceLab profile page.
Related Laboratory Equipment
Oxidation practicals with Sodium Dichromate typically draw on these reagents and apparatus:
- Sulphuric Acid Concentrated — acidifies the dichromate oxidising mixture.
- Distillation Apparatus — separates the aldehyde or ketone formed by oxidation.
- Liebig Condenser — condenses volatile products as they distil over.
- Sodium Chromate — the yellow chromate salt for chromate–dichromate equilibrium work.
- Potassium Dichromate — the non-hygroscopic alternative for titration standards.

Frequently Asked Questions
How is Sodium Dichromate different from Potassium Dichromate?
Sodium Dichromate is much more soluble in water than potassium dichromate, which suits concentrated oxidising mixtures, but it absorbs moisture from air. Potassium dichromate is therefore preferred for accurately weighed titration standards, while the sodium salt is favoured for preparative oxidations.
What reactions is Sodium Dichromate used for?
Sodium Dichromate acidified with sulphuric acid oxidises primary alcohols to aldehydes or carboxylic acids and secondary alcohols to ketones in college organic chemistry. It is also used to demonstrate the chromate–dichromate equilibrium and the colour change as chromium(VI) is reduced to chromium(III).
How should Sodium Dichromate be stored?
Keep Sodium Dichromate in a tightly sealed container inside a dry, locked oxidiser cabinet, because it picks up moisture and reacts strongly with organic materials. Store it away from solvents, fuels and reducing agents and follow the storage section of the MSDS supplied with the pack.
What quantity of Sodium Dichromate is in each pack?
Each pack of Sodium Dichromate (SCI-487/208) contains 100 g of analytical reagent grade material, supplied with its MSDS. Laboratories that run oxidation practicals for several student batches can order multiple packs in a single quotation.
What is the shelf life of Sodium Dichromate?
Shelf life depends on the chemical, its grade and storage conditions, and because Sodium Dichromate absorbs moisture, good storage matters a great deal. Ask us for the expiry date of the batch you are quoted, and reseal the container immediately after each use.
Who supplies Sodium Dichromate to institutions?
Sodium Dichromate is supplied to schools, colleges, research institutes and dealers by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company handles quotations, packing and dispatch for buyers in India and international markets through a single point of contact.
