What is potassium iodide in chemistry?

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).

Is potassium iodide an organic compound?

Potassium iodide is an inorganic chemical compound which is denoted by the chemical formula KI.

How is potassium iodide made?

Potassium iodide (KI) is prepared by reacting iodine with a hot solution of potassium hydroxide. It is mainly used in the form of a saturated solution, 100 g of potassium iodide to 100 ml of water. This equates to approximately 50 mg/drop. The solution is usually added to water, fruit juice or milk before drinking.

What is the use of KI?

KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.

What type of bond is potassium iodide?

ionic bond
Potassium iodide (KI) forms an ionic bond. Potassium and iodine have very different electronegativities. The two atoms would form an ionic bond since ionic bonds form between atoms with a large difference in electronegativity (difference>1.7 using the Pauling scale will result in an ionic bond).

Is potassium iodide same as iodine?

Potassium iodide (KI) is the same form of iodine used to iodize table salt. KI floods the thyroid with iodine, thus preventing radioactive iodine from being absorbed. If taken at the proper time, KI protects the thyroid from radioactive iodine from all sources – air, food, milk, and water.

Is potassium iodide hazardous?

May be harmful if swallowed. Inhalation: May cause respiratory tract irritation. May be harmful if inhaled.

What is the polarity of potassium iodide?

Explanation: Potassium iodide (KI) forms an ionic bond….What type of bond is Ki?

Electronegativity (K)	0.8
Electronegativity (I)	2.7
Electronegativity Difference	1.9 Non-Polar Covalent = 0 0 < Polar Covalent < 2 Ionic (Non-Covalent) ≥ 2
Bond Type	Polar Covalent

Is Ki acidic or basic?

It is a neutral salt! Potassium will act as a spectator ion (as any group 1A element) and since the conjugate acid of I- is a strong acid (hydroiodic acid), it will also act as a spectator. Similarly with NaCl or KBr.

Is potassium iodide a good source of iodine?

What is a substitute for potassium iodide?

According to sources on the Internet, most supplies of KI are depleted and people are unable to purchase it. As an alternative, people may want to purchase Lugol’s Solution, which is a combination of pure iodine, Potassium iodide, and water.

Is potassium iodide and iodine the same thing?

What are the chemical properties of potassium iodide?

Chemical properties. Potassium iodide behaves as a simple ionic salt, K+I− . Since the iodide ion is a mild reducing agent, I− is easily oxidised to I2 by powerful oxidising agents such as chlorine: Even air will oxidize iodide as evidenced by the observation of a purple extract when KI is rinsed with dichloromethane.

What are the benefits of potassium iodide?

Potassium iodide’s health benefits. Numerous health benefits have been attributed to potassium iodide, such as: • Helping protect against the effects of radiation — As mentioned, potassium iodide can be used to block the damaging effects of radioactive iodine.

What are the products of potassium iodide?

Product(s) containing potassium iodide: potassium iodide systemic. Brand names: SSKI, Iosat, ThyroShield, Yodefan. Drug class(es): antithyroid agents, expectorants. Potassium iodide systemic is used in the treatment of: Cough. Cutaneous Sporotrichosis. Hyperthyroidism.
