Product Code : SCL-LC-12284
Ferrous Sulphate Green Crystal (SKU SCL-LC-12284) is iron(II) sulphate, commonly the green heptahydrate FeSO4·7H2O, for school and college chemistry: iron-salt reactions, sulphate tests, redox demonstrations, crystallisation and solution preparation. Science Lab Supplies prices and dispatches the crystals from Ambala, India, for schools, colleges, training institutes, tender contractors and distributors equipping a chemistry practical room.
Specifications
For the green crystals, the table gives identity, hydrate, air sensitivity, storage and documents a row each. In short, this is ferrous sulphate, most commonly the heptahydrate; iron(II) salts slowly oxidise in air and the colour can change when they do, so the hydrate form and condition are confirmed on the batch label.

Applications and Experiments for Ferrous Sulphate Green Crystal
The crystals can show Fe2+ ions, their oxidation to Fe3+, reducing-agent behaviour and water of crystallisation. Use freshly prepared solutions when Fe2+ stability matters, and keep opened stock dry in a Glass Desiccator. Wear a lab coat, gloves and eye protection, avoid dust and oxidising agents, and follow institutional waste rules.

Standard Scope of Supply
Each order line is one pack of the green crystals with a batch label, the Safety Data Sheet, shelf-life detail 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). An iron-salt or redox order can start as a note on the contact page or a basket in the enquiry cart; for board tenders, see the lab tender page.
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, working from Ambala, India, packs the crystals with a labelled batch and Safety Data Sheet and can fold them into 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, Redox Reagents and Titration Glassware
Iron-salt and redox practicals compare iron(II) with iron(III), use an oxidising agent or ferricyanide to show the change, and need a burette for the titration. These items, including metallic iron and a second sulphate, can be added to one quotation with the green crystals.
