What’s an oxidation state?
When an element or compound is dissolved in water, it’s in the ionic form, meaning the element or compound carries either a positive or negative charge. Ions that are positively charged (one or more electrons have been removed) are known as cations. Negatively charged ions (one or more electrons have been added) are known as anions. The charge of an element or compound can affect its toxicity in the human body as well as its solubility (how well it dissolves) in water.
