In Iodine, the element is in 0 oxidation state, but in Iodide it is in -1.
Iodine = I2 , Iodide = I-
Iodine can exist freely, but Iodide cannot.
iodide is a compound which contains iodine whereas chloride is one with chlorine
iodine is a neutral molecule I2. and iodide is a negative charged ion I-. Iodine=Heavy rare element. Iodide=Compounds with iodine in formal oxidation state. I am pretty sure Iodine the the elemental name, but in reference to a compound Eg potassium iodide, you change the ending.
You can separate a mixture of iodine solid and sodium iodide by using the difference in solubility of the two compounds. Since sodium iodide is soluble in water while iodine is not, you can dissolve the mixture in water to dissolve the sodium iodide, leaving the solid iodine behind. The two can then be separated by filtration.
iodine and iron
The iodine stain solution you're referring to might be Lugol's iodine. This is iodine and potassium iodide in water. The product available in a pharmacy is tincture of iodine which is iodine and potassium iodide in ethanol and water. Please see the links.
No, iodide is an ion formed by the nonmetal iodine.
Three compounds of iodine are potassium iodide (KI), iodine pentafluoride (IF5), and hydrogen iodide (HI).
Iodide is an ion formed from the element iodine, so it is not a compound.
Yes. "Potassium Iodine" tablets is a colloquial - and incorrect - way of saying "Potassium Iodide" tablets.
Iodide is iodine with a negative charge, and is thus written as I-.
The word equation for the reaction between potassium and iodine is: potassium + iodine → potassium iodide.
When iodide reacts with chlorine, it forms iodine gas according to the chemical equation: 2KI + Cl2 → 2KCl + I2. This is a redox reaction where chlorine is reduced and iodide is oxidized. The reaction can be seen as the displacement of iodine from the iodide by chlorine.
