What is the most frequently asked questions about iodine potassium iodide

What is iodine potassium iodide solution?

Lugol’s iodine , also known as aqueous iodine and strong iodine solution , is a solution of potassium iodide with iodine in water. Taken by mouth it is used to treat thyrotoxicosis until surgery can be carried out, protect the thyroid gland from radioactive iodine, and to treat iodine deficiency.

What color is iodine potassium iodide?

Iodine – KI Reagent: Iodine is not very soluble in water, therefore the iodine reagent is made by dissolving iodine in water in the presence of potassium iodide. This makes a linear triiodide ion complex with is soluble that slips into the coil of the starch causing an intense blue – black color.

How to make iodine potassium iodide solution?

Iodine 0.1 N: Weigh 40 g of potassium iodide (KI) in a 500 mL glass-stoppered flask and dissolve in 100 mL of purified water. Let the solution come to room temperature, add 12.7 g of resublimed iodine (I2), restopper the flask, and swirl the flask until the iodine is completely dissolved.

When iodine dissolved in potassium iodide?

The I2 molecules in iodine are not very soluble in water because they are not alike. I2 is non-polar whereas H2O is polar. But KI solution contains I- ions which combine with the I2 molecules to form I3- ions because these are charged they dissolve in the water which is a polar solvent.

What is iodine potassium iodide used for?

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.

Is iodine and potassium iodide the same thing?

Iodide is the ion state of iodine , occurring when iodine bonds with another element, such as potassium . So iodine and iodide are simply different expressions of the same element. Iodides simply represent a safe form of iodine for ingestion.

What is iodine potassium iodide?

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 .
