as ions they are named Iodide.... charge is -1
a bromide ion is formed, the ion formed has a -1 charge, and the ion formed is an anion
banana
Oxygen ion has a charge -2
On addition of the KI to your copper (II) solution, you formed Copper (I) iodine solid and produced the tri-iodide ion. It is the tri-iodide ion that you are titrating with the sodium thiosulfate. The tri-iodine ion is what itercalates into the starch molecules to form the dark blue color you are using as an end point in the titration. Some the the tri-iodide ion formed will adsorb to the surface of the solid copper (I) iodine formed. This must be desorbed for a complete titration. The addition of the potassium thiocyanate, displaces the adsorbed tri-iodine ion, and liberates it for titration.

Iodide is monovalent anion. It is I+The charge of the iodide ion is 1-
I-
-3
+1 Na+ ion is formed
No, iodide is an ion formed by the nonmetal iodine.
Magnesium once formed an ion the charge is 2+ .
a bromide ion is formed, the ion formed has a -1 charge, and the ion formed is an anion
-2 is the most common charge (sulphide 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.
