Potassium Sulfocyanur (Product Code: SCI-733/322), better known as potassium thiocyanate (KSCN), is an analytical reagent grade salt used to demonstrate chemical equilibrium and to detect iron(III) in school and college chemistry laboratories. Supplied as a 100 g pack with its MSDS, it is the thiocyanate commonly used for the iron(III)–thiocyanate equilibrium experiment. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, together with the chemistry lab equipment such practicals need.

Mixing dilute iron(III) chloride with potassium thiocyanate gives a blood-red complex in equilibrium with the pale starting ions, so students can watch Le Chatelier's principle at work: adding more thiocyanate or more iron(III) deepens the colour, while adding silver nitrate, which removes thiocyanate as a white precipitate, makes it fade. Splitting one red solution across a row of test tubes and changing one condition in each makes an efficient class practical.
In quantitative analysis, potassium thiocyanate is the titrant in Volhard's method: chloride in a sample is precipitated with a measured excess of silver nitrate, and the leftover silver is titrated with thiocyanate until an iron(III) indicator turns red. The same red colour gives a quick qualitative check for iron(III) in water or dissolved rust. Keep the salt away from acids and wear gloves when making up solutions.
ScienceLab, the brand of Jain Scientific Equipments Private Limited in Ambala, supplies Potassium Sulfocyanur in 100 g packs with the MSDS for equilibrium, analysis and inorganic chemistry practicals. The company can quote it together with iron(III) chloride, silver nitrate and burettes for schools, colleges, dealers and importers in India and international markets.

Is Potassium Sulfocyanur the same as potassium thiocyanate?
Yes. Potassium Sulfocyanur SCI-733/322 is potassium thiocyanate, KSCN, sometimes called potassium sulfocyanide. It is supplied as a 100 g analytical reagent pack with its MSDS for equilibrium practicals, iron(III) tests and Volhard titrations in school and college laboratories.
How does Potassium Sulfocyanur demonstrate Le Chatelier's principle?
Potassium Sulfocyanur forms a blood-red complex with iron(III) that exists in equilibrium with the separate ions. Adding more thiocyanate or iron(III) deepens the red, while adding silver nitrate removes thiocyanate and makes the colour fade, showing how an equilibrium responds to changes.
What is Volhard's method with Potassium Sulfocyanur?
In Volhard's method, chloride is precipitated with a known excess of silver nitrate and the unused silver is titrated with Potassium Sulfocyanur solution. An iron(III) indicator turns red at the end point, allowing the chloride content of the sample to be calculated.
How should Potassium Sulfocyanur be stored?
Keep Potassium Sulfocyanur SCI-733/322 tightly closed in a dry place, away from acids and strong oxidisers, as it takes up moisture from the air. 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 Potassium Sulfocyanur SCI-733/322?
Potassium Sulfocyanur SCI-733/322 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the reagent and sends it with its MSDS to schools, colleges, analytical laboratories, dealers and importers in India and international markets.
What should a Potassium Sulfocyanur enquiry include?
A Potassium Sulfocyanur enquiry should include the product code SCI-733/322, the number of 100 g packs, the delivery location and whether you also need iron(III) chloride, silver nitrate or burettes. Send it through the contact page or the enquiry cart for a quotation.
Ask for Potassium Sulfocyanur on the ScienceLab contact page or add it to the enquiry cart with the iron(III) chloride and silver nitrate for your equilibrium and titration sessions.
