As such, it is found dissolved inseawater , and is part of many minerals.Most industrial chemical applications of potassium employ the relativelyhigh solubility in water of potassium compounds, such as potassium soaps.Potassium metal has only a few special applications. Potassium ions arenecessary for the function of all living cells.
