PbI2
nitre, saltpeter(KNO3), Chile saltpeter(NaNO3)
The formula for bromine is Br2 and the formula for iodine is I2.
The chemical formula for the compound formed from iron (II) and iodine is FeI2. Iron (II) has a +2 charge, and iodine has a -1 charge, so the correct formula involves two iodine atoms for every iron atom to balance the charges.
The formula of iodine fluoride is IF3.
The formula for iodine water is I2 (molecular iodine) dissolved in water.
Pbl2
The correct name for the chemical formula I2 is diiodine.
Literally, the correct formula for potassium and iodine at standard temperature and pressure would be " K and I2". The formula for the compound formed between potassium and iodine, however, is KI.
The correct molecular formula for iodine pentafluoride is IF5. It consists of one iodine atom and five fluorine atoms in the compound.
When aqueous solutions of silver nitrate and sodium iodide [note correct spelling] are mixed, silver iodide solid precipitates from the mixture.
The formula of diiodine hexachloride is I2Cl6 or (ICl3)2. Both are correct.
