I-
No, iodide is an ion formed by the nonmetal iodine.
-2 is the most common charge (sulphide ion).
The most common ion formed by sulfur is the sulfide ion (S2-).
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.
An iodine ion is named based on its charge. If it has a -1 charge, it is called an iodide ion. If it has a +1 charge, it is called an iodine ion.
The most common charge for an iodine ion is -1.
Iodine typically forms a negatively charged ion called iodide (I-).
I^- is the most common ion of Iodine.
The ion formed from iodine would have a charge of -1, since iodine typically gains one electron to achieve a stable electron configuration.
as ions they are named Iodide.... charge is -1
No, iodide is an ion formed by the nonmetal iodine.
-2 is the most common charge (sulphide ion).
The most common ion formed by sulfur is the sulfide ion (S2-).
Ionic bond is formed between rubidium and iodine, where rubidium donates its electron to iodine to complete its valence shell. Rubidium becomes a positively charged ion (cation) and iodine becomes a negatively charged ion (anion), resulting in the formation of an ionic compound, rubidium iodide.
Iodine ion is not consumed; in the first step the iodine ion is oxidized to iodine, in the second step iodine is reduced to iodine ion.
