These are the ions and their charges: Fe+3 SO3-2The charges have to add up to zero, so two +3 iron ions cancel out three -2 sulfite:Fe+3 Fe+3 SO3-2 SO3-2 SO3-2Simplify: Fe2(SO3)3
These are the ions and their charges: Fe+3 S-2The charges have to add up to zero, so two +3 iron ions cancel out three -2 sulfur ions: Fe+3 Fe+3 S-2 S-2 S-2Simplify: Fe2S3

Iron ions, Fe+3, will bind to oxygen ions, O-2, in a ratio that depends on their charges since the total positive charges in the molecule must equal the total negative charges. The eventual number of positive and negative charges is found by the least common multiple of the charges. In this instance, the charges are 3 and 2. The least common multiple is 6, so two atoms of the Fe+3 are needed to have a total positivie charge of +6, and three O-2 are needed to have a total negative charge of -6 to provide the electrical balance. The resulting molecule is Fe2O3.
Fe+3 PO4-3 Fe+3 PO4-3 FePO4
Fe+3 SO3-2 ------> these are the ions and their charges. Sulfite's charge is -2 and Iron's charge is +3 (you know this because of the (III)Fe+3 Fe+3 SO3-2 SO3-2 SO3-2 ------> the charges have to add up to zero, so two +3 Fe ions equal +6 and three -2 Sulfite ions equal -6.Fe2(SO3)3 -----> simplify
Fe+3 CO3-2 *iron III carbonate is known as ferric carbonate
Fe+3 Cl-1 Fe+3 Cl-1 Cl-1 Cl-1 FeCl3
Iron(II) compounds contain ions with 2 positive charges, iron(III) ions have 3 positive charges.
Fe(OH)2 How is it formed? Fe2+ + (OH) 1- = Fe(OH)2 *remember to use subscripts Remember to criss cross the charges. Fe has a charge of 2 and hydroxide (polyatomic) has a charge of -1. So your final product is Fe(OH)2 always put the OH in brackets because the 2 applies to everything in the brackets.
Fe+2 SO4-2 <----- these are the ions and their charges. The charges have to add up to zero, so one +2 iron ion cancels out one -2 sulfate ion. FeSO4 <--- simplify
These are the ions and their charges: Fe+2 SO4-2. The charges have to add up to zero, so one +2 iron ion cancels out one -2 sulfate ion. Therefore, the formula is FeSO4

Fe = iron SO3 = sulfite Iron (II) sulfite Transition metals always need roman numerals to represent their charges.
Fe(HSO3)3 Fe3+ + HSO3- Whenever you add the hydrogen atom you lose one of the negative charges.
