Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a ...

Cations can be identified with flame tests or precipitate tests using sodium hydroxide and ammonia solutions. Anions (halide, sulfate, and carbonate ions) can be identified using precipitate tests ...

Salts are natural components of soil, surface, and groundwater. They are ionic mineral compounds, which means they bonded by electrostatic attractions between cations (+ charge) and anions (- charge).
