Depends on if you have iron (II) iodide or iron (III) iodide.
iron (II) iodide is FeI2, while iron (III) iodide is FeI3.
The formula for iridium(III) iodide is IrI3. This compound is a chemical combination of iridium with a +3 oxidation state and iodine.
Aluminum (III) Iodide the aluminum uses it's +3 oxidation state therefore it is named Aluminum (III) and since it is ionic the Iodine just uses Iodide
When scandium reacts with iodine, it will form the ionic compound scandium(III) iodide, with the formula ScI3. Scandium typically forms ionic compounds in which it loses its 3 valence electrons to achieve a stable octet configuration.
Formula: Ir2(CO3)3
The ionic compound for iodine and aluminum is aluminum iodide, with the chemical formula AlI3. Aluminum has a 3+ charge and iodine has a 1- charge, so three iodine atoms are needed to balance the charge of one aluminum atom.
Formula: [Ir3+][I-]3
The formula for iridium(III) iodide is IrI3. This compound is a chemical combination of iridium with a +3 oxidation state and iodine.
Aluminum (III) Iodide the aluminum uses it's +3 oxidation state therefore it is named Aluminum (III) and since it is ionic the Iodine just uses Iodide
When scandium reacts with iodine, it will form the ionic compound scandium(III) iodide, with the formula ScI3. Scandium typically forms ionic compounds in which it loses its 3 valence electrons to achieve a stable octet configuration.
The chemical formula of aluminium iodide is AlI3.
Formula: Ir2(CO3)3
Formula: [S(CH3)3]I
Calcium iodide is an ionic compound composed of one calcium ion (Ca2+) and two iodide ions (I-). Therefore, there are a total of 3 ions present in calcium iodide.
AI Aluminum iodide: The chemical formula is AlI3 In solution 4 ions: Al3+ an 3 I- (iodide)
The ionic compound for iodine and aluminum is aluminum iodide, with the chemical formula AlI3. Aluminum has a 3+ charge and iodine has a 1- charge, so three iodine atoms are needed to balance the charge of one aluminum atom.
The chemical formula for cobalt(III) iodide is CoI3. Visit shrinke.me/Z3JN8dPM for other chemical formulas.
