What is Sodium Iodide

Sodium iodide is an inorganic sodium salt and an iodide salt. It is a white, water-soluble solid made up of a 1:1 mixture of sodium cations (Na+) and iodide anions (I) in a crystal lattice under normal circumstances. It is a chaotropic salt.

It is a strong deliquescent, which absorbs moisture and transforms into a solution. It is produced by the addition of sodium hydroxide or sodium carbonate to hydroiodic acid. Its primary applications in medicine are as nutritional supplements and additives.

Uses

• It is used to treat and prevent iodine deficiency.
• It is used in organic synthesis for the conversion of alkyl chlorides into alkyl iodides ( Finkelstein reaction).
• Some radioactive iodide salts of sodium, including Na¹²⁵I and Na¹³¹I, are used in the treatment of thyroid cancer and hyperthyroidism or as a radioactive tracer in imaging.
• Sodium iodide activated with Thallium is used in Scintillation detectors.

• Swelling of lymph glands

On Long-term usage:

• Headache (severe)
• Stomach irritation
• Soreness of teeth and gums
• Burning of mouth or throat

FAQs

Q. Is Sodium Iodide ionic or covalent?

Sodium iodide is a water-soluble ionic compound with a crystal lattice.

Q. Where to buy Sodium Iodide?

Macsen Labs is a leading supplier of high-quality Sodium Iodide with ISO certification.

Q. Is Sodium iodide soluble in water?

Sodium Iodide is soluble in water, ethanol and acetone.

Q. Is sodium iodide the same as salt?

Salt is chemically sodium chloride. The major distinction between sodium chloride and sodium iodide is that the former consists of an ion of chloride bound to a sodium ion, whereas the latter consists of an ion of iodide.
