Ammonium Iodide 98%

Ammonium iodide is an inorganic compound with a range of interesting properties and applications. Here's a more detailed description:

Chemical Properties and Structure:

• Composition:
  • It consists of ammonium cations (NH₄⁺) and iodide anions (I⁻), held together by ionic bonds.
  • The chemical formula is NH₄I.
• Appearance:
  • In its pure form, it appears as a white crystalline powder.
  • However, due to decomposition in air and light, it can often appear yellowish or brownish, as iodine is released.
• Solubility:
  • It is highly soluble in water.
  • It is also soluble in ethanol and other polar solvents.
• Stability:
  • Ammonium iodide is hygroscopic, meaning it readily absorbs moisture from the air.
  • It is sensitive to light and air, leading to decomposition and the release of iodine.
  • When heated it decomposes, releasing toxic fumes.

Physical Properties:

• Density:
  • Approximately 2.51 g/cm³.
• Melting Point:
  • 551 °C (sublimes).
• Boiling Point:
  • around 235 °C (in a vacuum) Variations do occur dependant on the conditions.
• It has no real distinct odor.

Uses and Applications:

• Pharmaceuticals:
  • It has been used in some medicinal applications.
• Photographic Chemicals:
  • It has historical applications in photographic processes.
• Chemical Synthesis:
  • It can be used as a reagent in various chemical reactions.
  • It has been seen being used in organic syntheses, as a form of iodination.
• It is used in some applications for weather modification.

Hazards:

• Ammonium iodide can cause irritation to the skin, eyes, and respiratory system.
• When heated, it decomposes, releasing toxic fumes, including hydrogen iodide, ammonia, and nitrogen oxides.
• When handled proper care and ventilation should be used.
