What is potassium iodide and what is it used for?

Potassium iodide (KI) is a chemical compound that can be used to protect the thyroid gland from possible radiation injury caused by radioactive iodine (radioiodine). Some radiological emergencies may release large amounts of radioiodine to the environment.

Potassium iodide is used to loosen and break up mucus in the airways. This helps you cough up the mucus so you can breathe more easily if you have long-term lung problems (such as asthma, chronic bronchitis, emphysema). This medication is known as an expectorant.

What is potassium iodide crystals benefits?

Potassium iodide is used to loosen and break up mucus in the airways. This helps you cough up the mucus so you can breathe more easily if you have long-term lung problems (such as asthmachronic bronchitisemphysema). This medication is known as an expectorant.Potassium iodide is also used along with antithyroid medicines to prepare the thyroid gland for surgical removal, to treat certain overactive thyroid conditions (hyperthyroidism), and to protect the thyroid in a radiation exposure emergency.

It works by shrinking the size of the thyroid gland and decreasing the amount of thyroid hormones produced.In a radiation emergency, potassium iodide blocks only the thyroid from absorbing radioactive iodine, protecting it from damage and reducing the risk of thyroid cancer. Use this medication along with other emergency measures that will be recommended to you by public health and safety officials (such as finding safe shelter, evacuation, controlling food supply).

hydrogen peroxide and potassium iodide

What happens when you mix hydrogen peroxide and potassium iodide?

Brief Description: Two solutions are mixed resulting in an eruption of foam resembling a huge stream of toothpaste. This is the classic “Elephant Toothpaste” reaction.

In this experiment, we will use the iodide ion (I) present in potassium iodide or sodium iodide as a catalyst to speed up the decomposition of hydrogen peroxide. The reaction is also exothermic, meaning that it releases heat.

What happens when Lead Nitrate  and  Potassium Iodide?


Lead Nitrate with Potassium Iodide

  • Lead(II) nitrate (Pb(NO3)2) interacts with potassium iodide (KI) to form Lead(II) iodide (PbI2) and Potassium nitrate (KNO3).
  • This reaction can be considered a displacement reaction.



  • Potassium nitrate dissolves in water.
  • Lead(II) iodide, on the other hand, is only moderately soluble in water.
  • The majority of the lead(II) iodide in the solution precipitates out as a yellow solid.
