Web20 mrt. 2024 · An ion is a molecule that has a positive or a negative charge; iron ions, for example, have a positive charge. One way to effectively purify water is to remove these ions and replace them with hydrogen (H+) and … WebBicarbonate ions result from a chemical reaction that starts with carbon dioxide (CO 2) and water, two molecules that are produced at the end of aerobic metabolism. Only a small amount of CO 2 can be dissolved in body fluids. Thus, over 90 percent of the CO 2 is converted into bicarbonate ions, HCO 3 –, through the following reactions:
