\n
The ammonium ion NH4+<\/strong> has a charge of +1. Since there are two ammonium ions in the compound, the total contribution to the charge from the ammonium ions is +2.<\/li>\n\n\n\n
The sulfate ion has a charge of -2. Since there are two sulfate ions in the compound, the total contribution to the charge from the sulfate ions is -4.<\/li>\n\n\n\n
The entire compound Fe(NH4)2(SO4)2<\/strong> must have a neutral charge because no charge is indicated for the overall molecule. Therefore, the sum of the oxidation states of all components must equal zero.<\/li>\n<\/ol>\n\n\n\n\n
