Over 60% of the human body is water, and within this water are crucial dissolved electrolytes. Understanding **how to tell if something is a good electrolyte** involves examining its ability to conduct electricity in solution, which is directly tied to its degree of ionization.

According to the reactivity series of metals, potassium is ranked significantly higher than iron, meaning it is more reactive. This fundamental principle of chemistry allows us to answer the question: can potassium displace iron? The answer lies in the relative position of these two elements within this vital chemical hierarchy.
