Guida verificata passo dopo passo1
Identify the metal in the compound FeCl_3, which is iron (Fe).
Determine the charge on the chloride ion (Cl), which is -1.
Since there are three chloride ions, the total negative charge is 3 × (-1) = -3.
To balance the charges, the iron must have a charge of +3, indicating the oxidation state of iron is +3.
Name the compound using the Stock system, which includes the metal name followed by its oxidation state in Roman numerals in parentheses, resulting in Iron(III) chloride.
