Sodium Thiocyanate
Sodium Thiocyanate (Product Code: SCL-971/228) is an analytical reagent grade thiocyanate salt used to detect iron(III) ions and to demonstrate chemical equilibrium in school and college chemistry laboratories. Teachers and lab assistants rely on the blood-red colour it forms with ferric iron, and it comes as a 500 gm pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India for teaching laboratories.

What Is Sodium Thiocyanate Used For?
For cation identification, a few drops of thiocyanate solution are added to the acidified test solution: an immediate blood-red colour from the iron-thiocyanate complex confirms iron(III). Iron(II) gives little colour until it is oxidised, so the test also helps students tell the two oxidation states apart. With cobalt(II), a concentrated thiocyanate solution and a little acetone develop a blue complex, a further confirmatory test used in college analysis.
The same reaction drives a much-used Le Chatelier's principle practical and features in many a chemistry teaching kit in India. A pale red mixture of dilute ferric chloride and thiocyanate is shared among several tubes; adding more iron(III) or more thiocyanate deepens the colour, while removing iron(III) or changing temperature shifts it the other way. Sodium thiocyanate is harmful if swallowed or absorbed, and contact with acids can release a very toxic gas, so keep it apart from acids and wash hands after use. The solid absorbs moisture from air, so close the container promptly.
Supplier
Sodium Thiocyanate is sourced and supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades as ScienceLab. Schools, colleges, university departments and dealers can order it together with other reagents and laboratory apparatus in a single enquiry, for delivery in India and international markets. More about the company is on the ScienceLab company profile.

Frequently Asked Questions
Will Sodium Thiocyanate detect iron(II)?
Not directly. Sodium thiocyanate gives only a faint colour with iron(II), so oxidise the sample first, for example with a drop of hydrogen peroxide, and then add the thiocyanate solution to see the blood-red iron(III) complex that confirms iron.
How is Sodium Thiocyanate used to teach chemical equilibrium?
Sodium thiocyanate is mixed with dilute iron(III) solution to give a pale red complex; students then add extra reactant, remove iron(III) or warm the tubes, and relate each colour change to the shift in equilibrium predicted by Le Chatelier's principle.
Why has the Sodium Thiocyanate become damp or caked?
Because sodium thiocyanate is strongly hygroscopic and pulls moisture from room air whenever the lid is open. Caking does not stop it working in qualitative tests, but storing the pack tightly closed in a dry cupboard prevents it.
What precautions does Sodium Thiocyanate need?
Sodium thiocyanate should not be swallowed, spilled on skin or inhaled as dust, and it must never be stored with or mixed into acids, which can release a very toxic gas. The MSDS supplied with the pack covers protective equipment, first aid and disposal.
What is the shelf life of Sodium Thiocyanate?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is stated for this sodium thiocyanate. Ask us for the expiry date of the batch you are quoted, and keep the opened pack sealed and dry.
Who supplies Sodium Thiocyanate?
Sodium Thiocyanate is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India. The company sources this analytical reagent for schools, colleges, universities and dealers in India and international markets, and quotes it alongside other chemistry reagents.
Can several departments order Sodium Thiocyanate together?
Yes. Tell us how many 500 gm packs of sodium thiocyanate each department needs and the delivery points through the contact form, and we will prepare one consolidated quotation for the full list.
