Potassium Iodide ER Qualigens 100g

Potassium Iodide ER Qualigens 100g About

• The chemical formula for potassium iodide is KI. 
• It's an ionic compound formed by the electrostatic attraction between potassium cations (K+) and iodide anions (I-). 
• The structure is similar to sodium chloride (NaCl), with each potassium ion surrounded by six iodide ions and vice versa, according to the cubic crystal system. 

• Appearance: Colorless to white, cubical crystals or powder.
• Taste: Saline and bitter.
• Solubility: Highly soluble in water, also soluble in alcohol, acetone, and glycerol.
• Hygroscopic: Absorbs moisture from the air and can be slightly deliquescent.
• Oxidation: Can oxidize in air, turning yellow due to the formation of potassium carbonate and elemental iodine.
• Melting Point: 680C (1258F).
• Boiling Point: 1330C (2426F). 

• Potassium iodide is typically prepared by reacting potassium hydroxide with iodine. 
• It can also be produced by reacting hydrogen iodide with potassium bicarbonate. 
• Industrially, it can be made by reacting potassium carbonate with iodine. 

• Medicine:Used as a nutritional supplement, expectorant, and in the treatment of certain thyroid conditions and skin disorders. 
• Nuclear Radiation:In a nuclear emergency, potassium iodide can protect the thyroid gland from radioactive iodine. 
• Industrial:Used as a reagent in iodometric titrations, in film photography, and as an additive in table salt (to prevent iodine deficiency).
