What is the molarity of iodine?
The molecular mass of iodine (I2) is 253.8 g/mol so the number of moles in 2 g is 0.0079 mol (2 g/253.8 g/mol). And the molar concentration of iodine is 0.0079 mol/0.1 L or 0.079 M.
What is a iodine used for?
Today, iodine has many commercial uses. Iodide salts are used in pharmaceuticals and disinfectants, printing inks and dyes, catalysts, animal feed supplements and photographic chemicals. Iodine is also used to make polarising filters for LCD displays.

Is iodine safe to take?
When taken by mouth: Iodine is LIKELY SAFE for most people when taken by mouth at recommended amounts. Side effects may include nausea and stomach pain, runny nose, headache, metallic taste, and diarrhea.
Is iodine good for skin?
Iodine regulates skin moisture levels and aids in the healing of cuts and scars through cellular regeneration. Iodine also regulates the hormones responsible for acne breakouts.
How can we prepare 0.1 M KI 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.
How do you make a 0.005 M solution of iodine?
Iodine solution: (0.005 mol L-1). Weigh 2 g of potassium iodide into a 100 mL beaker. Weigh 1.3 g of iodine and add it into the same beaker. Add a few mL of distilled water and swirl for a few minutes until iodine is dissolved.

Is I2 a solid or iodine I?
There are two forms of iodine, elemental diatomic iodine (I2) and ionic monoatomic iodide (I-). Several iodine supplement brands list both forms of iodine on their label. I2, elemental iodine, consists of two iodine atoms covalently bound together.
