Potassium Ferrocyanide

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, complex-ion teaching and reagent preparation. It suits salt-analysis practicals in schools, colleges and science departments. Orders for schools, colleges, training institutes, tender contractors and distributors are priced and dispatched by Science Lab Supplies from its Ambala, India base.

Specifications

Formula, hydrate options and handling limits for potassium ferrocyanide each take one row of the table. In short, it is K4[Fe(CN)6]·xH2O, often the trihydrate K4[Fe(CN)6]·3H2O though anhydrous and solution forms exist, and it is a different reagent from potassium ferricyanide; hydrate form, grade and pack size are confirmed on the label and quotation.

Applications and Experiments for Potassium Ferrocyanide

The reagent can be used in supervised qualitative inorganic demonstrations and as a worked example of a complex salt, to explain iron complex formation, coordination number, ligands and the naming of complex ions. Comparative lessons can set it beside potassium ferricyanide, provided the two reagents are clearly distinguished.

• Class 11–12 chemistry practicals: qualitative inorganic analysis, with test solutions dispensed from a Glass Bottle, with Dropper 60ml.
• 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, weighing the salt with a clean, dry Spatula.

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.

As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. For prices, contact us through the contact page or shortlist items in the enquiry cart; requests linked to a tender are handled through the lab tender page.

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. Wear gloves and Safety Glasses and work under supervision.

Who supplies the Potassium Ferrocyanide?
Potassium ferrocyanide is available from Science Lab Supplies in Ambala, which acts as a laboratory chemicals supplier in India; every school, college or distributor order has its hydrate form and pack size confirmed on the quotation.

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, so formula weight can be checked before solutions are prepared.
