Product Code : SCL-LC-12284
Ferrous Sulphate Green Crystal (SKU SCL-LC-12284) is iron(II) sulphate, commonly the green heptahydrate FeSO4·7H2O, used in school and college chemistry for iron-salt reactions, sulphate tests, redox demonstrations, crystallisation and solution preparation. Science Lab Supplies supplies the crystals from Ambala, India, to schools, colleges, training institutes, tender contractors and distributors as part of its school chemistry lab equipment in India.
Specifications
The product is ferrous sulphate supplied as green crystals, most commonly the heptahydrate. Ferrous salts slowly oxidise in air and the colour can change if this happens, so the hydrate form and condition are confirmed on the batch label. Grade, assay and pack size are stated on the quotation.

Applications and Experiments for Ferrous Sulphate Green Crystal
Teachers use the crystals to show Fe2+ ions, their oxidation to Fe3+, reducing-agent behaviour and water of crystallisation. Use freshly prepared solutions when Fe2+ stability matters. Wear a lab coat, gloves and eye protection, avoid dust and mixing with oxidising agents, and follow institutional waste rules.
- NCERT Class 10 science, Chapter 1: heating ferrous sulphate crystals as a decomposition reaction, performed by the teacher in a ventilated area.
- NCERT Class 10 science, Chapter 3: metal reactivity using ferrous sulphate solution.
- CBSE Class 12 practicals: preparing the double salt ferrous ammonium sulphate (Mohr’s salt).
- B.Sc. practicals: redox titrations and iron(II) salt chemistry.
Standard Scope of Supply
Each order line is one pack of the green crystals with a batch label, the 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. Keep the pack tightly closed between uses.
Packing, MOQ and Lead Time
A school can ask for a single pack and a purchasing board for bulk quantities; either way the quotation covers packing, delivery time and price for the amount requested. Titration glassware and other iron or sulphate salts may be quoted alongside it.
Under its Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Ask questions via the contact page, collect a list in the enquiry cart, or follow the lab tender page for tenders.
Frequently Asked Questions
Is ferrous sulphate the same as ferric sulphate?
No. Ferrous sulphate contains iron(II) and ferric sulphate contains iron(III). They behave differently in reactions and should not be interchanged unless the method allows it.
Why are the crystals green?
The green colour is typical of ferrous sulphate heptahydrate. The colour may change if the crystals oxidise in air or if a different hydrate form is supplied, so keep the pack closed.
Who supplies the Ferrous Sulphate Green Crystal?
Science Lab Supplies supplies the crystals from Ambala, India, with a labelled batch and Safety Data Sheet, and can include them on a wider chemistry quotation.
Is it suitable for school chemistry labs?
Yes, for supervised school and college practicals. Heating demonstrations should be run by the teacher with ventilation, and students should avoid dust, ingestion and eye contact.
Related Iron Salts and Redox Reagents
Iron-salt and redox practicals compare iron(II) with iron(III) and use an oxidising agent to show the change. These four items come from the same Lab Chemicals range and can be added to one quotation with the green crystals for a complete bench set.
- Ferric Sulphate — iron(III) sulphate, Fe2(SO4)3, for comparison with the ferrous salt.
- Ferric Chloride Lab Reagent — iron(III) chloride, FeCl3, for iron salt studies.
- Potassium Dichromate — chromium(VI) oxidising agent for redox titration work.
- Copper Sulphate Blue Crystal — copper(II) sulphate for crystallisation and hydration lessons.
