Product Code : SCL-LC-12295
Copper Sulphate Blue Crystal (SKU SCL-LC-12295) is copper(II) sulphate in the familiar blue crystalline form, sometimes called blue vitriol. With it, students can carry out crystallisation, water-of-crystallisation and displacement experiments, copper-ion tests and simple cells, in practicals from middle school to college. Packs of these crystals are supplied by Science Lab Supplies out of Ambala, India, to schools, colleges, tender contractors and distributors on request.
Specifications
The table lists each detail of the blue copper sulphate crystals separately. Briefly, they are normally the pentahydrate, CuSO4·5H2O, while anhydrous CuSO4 differs in appearance, molecular weight and handling, so the two should not be swapped without checking the method; hydrate form, grade and crystal size are confirmed on the quotation.

Applications and Experiments for Copper Sulphate Crystals
The crystals serve several standard practicals. They turn white when heated as their water of crystallisation is driven off, grow back from a saturated solution, and give a blue solution in which iron or zinc displaces copper. The same solution supplies copper ions for analysis and electrochemistry.
- Class 7 science: crystallisation of copper sulphate, evaporating a little solution on a Watch Glass.
- Class 10 science: displacement of copper by Iron Metal Turnings / Filings, and heating the crystals in a tube gripped by a Test Tube Holder with Handle.
- Class 12 chemistry: copper half-cells in electrochemistry practicals.
- Salt analysis: tests for the copper(II) ion and the sulphate ion.
Standard Scope of Supply
Supply is one pack of blue crystals in the quantity quoted, labelled with batch and hazard information and sent with 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.
Packing, MOQ and Lead Time
Ask for a single pack or for a quantity sized to every class that runs these practicals; the quotation spells out packing, delivery time and price for that amount. Iron filings, zinc salts and other chemistry lab equipment in India can be included in the same quotation.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. To have the crystals priced, describe your order on the contact page or drop them into the enquiry cart beside other reagents; the lab tender page covers purchases made under a tender.
Frequently Asked Questions
Why do copper sulphate crystals turn white when heated?
Heating drives off the water of crystallisation, leaving white anhydrous copper sulphate. Adding water back restores the blue colour, which is why the crystals are used to teach hydrated salts.
Is blue copper sulphate the same as anhydrous copper sulphate?
No. The blue crystals are normally the pentahydrate, CuSO4·5H2O, while the anhydrous salt is CuSO4. They differ in appearance and formula weight, so check which one a method calls for.
Is copper sulphate hazardous?
It must be handled with care: avoid swallowing it, breathing its dust and contact with eyes and skin, and collect copper-containing solutions as chemical waste rather than pouring them into drains.
Who supplies the Copper Sulphate Blue Crystal?
Science Lab Supplies, working from Ambala in India, takes enquiries for copper sulphate crystals for schools and colleges and replies with a quotation that confirms the hydrate form, grade and pack size of the batch on offer.
