Question

What is the charge on the iron cations in $iron(||)chloride$ and $iron(|||)chloride$ , respectively?

Answer 1

Hint: To know the charge on the iron cations in $iron(||)chloride$ and $iron(|||)chloride$ , we should go through the properties of given cations. We will also discuss more about the given iron cations.

Complete step by step answer:
The roman numerals after the name of the iron cation indicates the charge on the iron cation.
When naming ionic compounds which contain metal ions capable of forming more than one kind of cation, the Roman numeral after the metal’s name indicates the charge.
Therefore, the iron cation in $iron(||)chloride$ has a charge of ${2^ + }$ , and the charge on the iron cation in $iron(|||)chloride$ has a charge of ${3^ + }$ .

Both iron cation and carboxylate anion containing methane monooxygenase enzyme, which catalyzes the oxidation of methane to methanol, and the ribonucleotide reductase enzyme, which catalyzes the oxidation of a tyrosinase residue to a tyrosyl radical, have stimulated the preparation and study of new iron cation containing carboxylate complexes by inorganic coordination chemists.

Note: A cation is a positively charged ion, with fewer electrons than protons, while an anion is negatively charged, with more electrons than protons. Because of their opposite electric charges, cations and anions attract each other and readily form ionic compounds.
