Q. Which are mineral salts? Where in living beings can found mineral salts?
Ans. Mineral salts are simple inorganic substances made of metallic chemical elements, like sodium, iron, calcium, potassium and magnesium, or of non- metallic elements, like phosphorus and chlorine.
They can be found in non-solubilized form, as part of structures of the organism, like the calcium in bones. They can also be found solubilized in water, as ions: for example, the potassium and sodium cations within cells.
