What is the charge on the iron cations in iron(II) chloride and iron (III) chloride, respectively?
1 Answer
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(II) chloride has a charge of 2^+, and the charge on the iron cation in iron(III) chloride has a charge of 3^+'. 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(II) chloride has a charge of 2^+, and the charge on the iron cation in iron(III) chloride has a charge.
The Roman numerals after the name of the iron cation indicates the charge on the iron cation.
Explanation:
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(II) chloride has a charge of #2^+#, and the charge on the iron cation in iron(III) chloride has a charge of #3^+'#.
