Iodine Crystals Extra Pure- 250gm Packs

Iodine Crystals Extra Pure consist of elemental iodine, a halogen that occurs as diatomic molecules and is known for its dark, lustrous crystalline appearance and tendency to sublime into violet vapour. Iodine participates in redox reactions and forms characteristic complexes with certain substances, making it useful in qualitative analysis, analytical chemistry, and teaching demonstrations. It is used in selected reagent preparations and laboratory procedures where elemental iodine is specifically required. Iodine has limited solubility in water but dissolves more readily in solutions containing iodide, forming triiodide species. Handle the crystals in a well-ventilated area and protect them from heat, as vapour can irritate the eyes and respiratory tract.

Product Specifications

Frequently Asked Questions About Iodine Crystals Extra Pure

What are iodine crystals used for in laboratories?

Elemental iodine is used in selected reagent preparations, redox experiments, qualitative demonstrations, and analytical procedures. Use it only where the method specifies iodine and apply appropriate controls for its vapour and reactivity.

What is the chemical formula of iodine crystals?

Elemental iodine exists as diatomic molecules and has the molecular formula I2. Its empirical formula is I, and its molar mass is approximately 253.81 g/mol.

What is the CAS number of iodine?

The CAS Registry Number for elemental iodine is 7553-56-2. This is distinct from the identifiers for iodine solutions or compounds containing iodine.

Does iodine dissolve in water?

Iodine has low solubility in water. It dissolves more readily in solutions containing iodide ions, which can form triiodide. Solvent choice and preparation should follow the laboratory method.

How should iodine crystals be stored and handled?

Store tightly closed in a cool, dry, well-ventilated place, away from heat and incompatible substances. Avoid inhaling vapour or dust, use suitable gloves and eye protection, and handle with effective ventilation according to the SDS.

Storage Conditions for Iodine Crystals Extra Pure

Store in a tightly closed, compatible container in a cool, dry, well-ventilated area away from heat and incompatible chemicals. Protect from unnecessary exposure and follow the product SDS for any specific segregation requirements.

Precautions for Handling Iodine Crystals Extra Pure

Review the current SDS before use. Avoid breathing iodine vapour or dust and prevent eye and skin contact. Wear suitable gloves, protective clothing, and eye protection, and handle with effective ventilation or a fume hood as required. Follow institutional spill and waste procedures.
