Why does chlorine gas turn starch iodide paper blue?
Chlorine gas oxidizes some of the iodide ions in the paper to create iodine diatomic molecules. These molecules react with the iodide ions and the starch to form a charge-transfer complex, which has a striking blue color. It is thought that linear I3- and I5- ions occupy the center of the helix structure in the starch. These ions are formed by the reaction of molecular iodine with iodide ions.
When iodine becomes an ion is the ion larger or smaller?
Iodine gains one electron to form iodide ion. The size of iodide ion is larger than the size of iodine atom.
Is iodine a metal or non-metal and what ion does it form?
Iodine is a nonmetal and it forms the iodide ion, I-.
What is the chemical equation for the following chlorine gas reacts with solid sodium iodide to form solid sodium chloride and solid iodine?
Cl2(g) + 2NaI(s) --------> 2NaCl(s) + I2(s)
Would barium and iodine form an ionic solid?
Yes. Barium iodide is ionic
What happens when chlorine gas is added to potassium iodide solution?
When chlorine gas is bubbled into an aqueous solution of potassium iodide, some of the iodide ions are oxidized to iodine. The iodine molecules combine with iodide ions to form brown triiodide ion, I3-. In this demonstration, the aqueous solution is above a layer of carbon tetrachloride, in which iodine is quite soluble. The beautiful violet color of iodine can be seen as the iodine dissolves in the carbon tetrachloride layer. With excess chlorine, iodine reacts to form iodine monochloride, ICl, which is ruby red. The iodine monochloride reacts further to form iodine trichloride, ICl3, which is much lighter in color, causing the solution to be decolorized.
Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride.?
Yes, it is correct.
How do I Write the balanced equation in which potassium iodide reacts with chlorine to form potassium chloride and iodine?
you have to write... 2KI + Cl2 = 2KCl + I2
What is the obtained form of iodine?
Iodine (I), sodium iodide (NaI), potassium iodide (KI), hydroiodic acid (HI)

Balanced equation for Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride?
2KI + Cl2 = 2KCl + I2

Is iodine a metal or non-metal and what ion does it form?
Iodine is a nonmetal and it forms the iodide ion, I-.
Does iodine form a cation or a anion?
Iodine forms the iodide ion. It has a charge of negative 1 (-1)
What is the name of an iodine ion?
An iodide ion is an iodine atom with a −1 charge. Compounds with iodine in formal oxidation state −1 are called iodides. This can include ionic compounds such as caesium iodide or covalent compounds such as carbon tetraiodide.
Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride?
This is the correct answer: Cl2(g)+2KI(aq) = I2(s)+2KCl(aq)
Does aluminum plus iodine forms aluminum oxide?
Aluminum and oxygen form aluminum oxide. Aluminum and iodine form aluminum iodide.
