Web2. Ion exchange. One of the most effective ways to eliminate nitrates is to pass the water through an ion exchange process. Ion exchange is most commonly found in traditional water softeners, but the method can be used to eliminate contaminants other than just water hardness minerals. Web15 sep. 2024 · The oxygen atom has a 2− charge as an ion. To balance the positive and negative charges, we look to the least common multiple—6: two iron 3+ ions will give 6+, while three 2− oxygen ions will give 6−, thereby balancing the overall positive and negative charges. Thus, the formula for this ionic compound is \ce {Fe2O3}.
