Ferrous Sulphate Green Crystal – 500 gram Packs

Ferrous Sulphate Green Crystal, also known as Iron(II) Sulphate Heptahydrate or Green Vitriol, is an inorganic iron salt with the chemical formula FeSO₄·7H₂O. It contains iron in the +2 oxidation state and seven molecules of water of crystallization. This compound is commonly recognized by its characteristic pale green crystalline appearance and has a molecular weight of approximately 278.01 g/mol. Its aqueous solutions provide iron(II) ions for suitable oxidation–reduction reactions, qualitative analysis, and quantitative chemistry experiments. Ferrous Sulphate Green Crystal is relevant to school and college practicals, university laboratories, analytical testing, and selected research applications involving iron compounds. Its suitability depends on the required assay, laboratory grade, and experimental method. Correct storage is important because exposure to air and moisture can affect the material’s condition and promote changes in its iron(II) content.

What is the CAS number of Ferrous Sulphate Green Crystal?

The CAS Registry Number for ferrous sulphate heptahydrate is 7782-63-0. This identifier distinguishes the hydrated compound from anhydrous ferrous sulphate and other hydrate forms. Confirming the exact chemical form is important for purchasing, inventory records, and accurate analytical calculations.

Why are Ferrous Sulphate crystals green?

The characteristic green colour is associated with hydrated iron(II) ions in the crystal structure. Ferrous sulphate may change in appearance during storage if oxidation or other chemical changes occur. Significant changes in colour or physical condition should be assessed before the reagent is used in analytical work.

How should Ferrous Sulphate Green Crystal be stored and handled?

Store the crystals in a tightly closed, properly labelled container under the supplier’s recommended conditions. Protect the material from contamination and unnecessary exposure to air and moisture. Wear suitable protective equipment and follow the applicable Safety Data Sheet and institutional procedures for preparation, spill response, and waste disposal.

Storage Conditions for Ferrous Sulphate Green Crystal

Store Ferrous Sulphate Green Crystal in a tightly closed, compatible container in a cool, dry laboratory storage area, following the supplier’s recommended conditions. Protect the crystals from contamination, excessive moisture, and unnecessary exposure to air to help maintain their condition and iron(II) content. Keep the container properly labelled and segregate the reagent from incompatible chemicals in accordance with applicable safety guidance.

Precautions for Handling Ferrous Sulphate Green Crystal

Review the applicable Safety Data Sheet before handling. Wear suitable laboratory gloves, protective clothing, and safety goggles, and avoid inhaling dust or allowing unnecessary skin and eye contact. Use appropriate ventilation during weighing and transfer. Prepare solutions using validated procedures, prevent contamination, and follow institutional requirements for spill response, chemical waste disposal, and emergency management.
