Question

determining the formation of an iron chloride
experiment introduction
davis, a graduate student, designed an experiment to determine
the reaction occurring when solid iron is heated with a limited
quantity of chlorine gas.

as a transition metal, iron can form more than one charge.

which of these is not a potential charge for an iron ion?
fe³⁺
fe⁺
fe²⁺

Explanation:

Iron is a transition metal. Common oxidation states (charges) of iron ions are \( \text{Fe}^{2+} \) (ferrous) and \( \text{Fe}^{3+} \) (ferric). The \( \text{Fe}^+ \) ion is not a commonly observed or stable potential charge for iron ions compared to \( \text{Fe}^{2+} \) and \( \text{Fe}^{3+} \).

Answer:

B. \( \text{Fe}^+ \)
