Product Code : SCL-LC-12273
Potassium Ferrocyanide (SKU SCL-LC-12273), systematically potassium hexacyanoferrate(II), is an inorganic coordination compound used in supervised chemistry for qualitative analysis of metal ions, complex-ion teaching and reagent preparation. Schools, colleges and science departments use it in salt-analysis practicals. Science Lab Supplies, based in Ambala, India, supplies it to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The compound is written K4[Fe(CN)6]·xH2O and is often supplied as the trihydrate, K4[Fe(CN)6]·3H2O, although anhydrous and solution forms also exist. It is a different reagent from potassium ferricyanide. The hydrate form, grade and pack size are printed on the batch label and confirmed in the quotation.

Applications and Experiments for Potassium Ferrocyanide
Its main teaching use is as a test reagent in salt analysis, where its solution gives characteristic coloured precipitates with certain metal ions. It is also the standard textbook example of a complex salt, used to explain coordination number, ligands and the naming of complex ions.
- Class 11–12 chemistry practicals: confirmatory tests for cations such as iron(III) and copper(II) in salt analysis.
- Class 12 chemistry: coordination compounds, including IUPAC naming of K4[Fe(CN)6].
- B.Sc. inorganic chemistry: complex-ion chemistry and qualitative analysis.
- Preparing reagent solutions under the SOP and Safety Data Sheet.
Standard Scope of Supply
One pack of potassium ferrocyanide is supplied per unit, in the hydrate form and quantity shown on the quotation, labelled with batch and hazard information and sent with its Safety Data Sheet and transport documents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
Tell us whether you need a single pack or salt-analysis stock for many practical batches, and the quotation will state packing, delivery time and price for that quantity. The other salt-analysis reagents and school chemistry lab equipment in India on your list can be quoted at the same time.

Frequently Asked Questions
Is potassium ferrocyanide the same as potassium ferricyanide?
No. Potassium ferrocyanide is the iron(II) complex, K4[Fe(CN)6], and is a separate reagent from the ferricyanide. The two should not be interchanged, so check the label before use.
Is potassium ferrocyanide hazardous?
It needs Safety Data Sheet-based handling. Do not mix it with acids, heat it unnecessarily or breathe the dust, and store it away from acids, strong oxidisers and moisture. Use gloves and eye protection under supervision.
Who supplies the Potassium Ferrocyanide?
It is quoted and dispatched by Science Lab Supplies in Ambala, India, a laboratory chemicals supplier in India serving schools, colleges and distributors, with hydrate form and pack size confirmed per order.
Which form is supplied?
It is often the trihydrate, but anhydrous or solution forms are possible. The quotation and batch label state the form you receive.
