Potash vs. Potassium: Difference and Comparison
Edited by Muazma Batool — By Muneeza Rehman — Updated on September 25, 2023
Potash is a variety of mined and manufactured salts containing potassium, while potassium is a chemical element with the symbol K.
Difference Between Potash and Potassium
Potash and potassium, while often used interchangeably in common language, have distinct differences in terms of their chemical nature and applications. Potash refers to various potassium compounds and potassium-bearing materials, primarily derived from evaporite deposits and minerals. The name "potash" historically refers to the ash of plants, which was leached in pots to produce potassium carbonate. In contrast, potassium is a pure chemical element with the symbol K and atomic number 19. It's a soft, silvery-white metal that reacts rapidly with air and water.

Potash finds its main use in the agriculture sector as a fertilizer. Given that it's rich in potassium, which is an essential nutrient for plant growth, potash ensures plants get adequate potassium to thrive. On the other hand, potassium, as an element, has several applications, from being a key nutrient in our diet to being used in various industrial processes. As an alkali metal, it reacts violently with water producing hydroxide and hydrogen gas.

The process of obtaining potash usually involves mining and then processing the ore to extract the potassium salts. These salts, such as potassium chloride (KCl), potassium sulfate (K2SO4), or potassium carbonate (K2CO3), are what typically constitute potash in commercial settings. Potassium, being a basic element, is not "extracted" in the same sense but can be isolated from compounds and salts where it is a constituent, including from potash salts.

One can derive an interesting linguistic observation when comparing potash and potassium. "Potash" has its origins in the method of leaching plant ashes in pots. "Potassium," on the other hand, gets its name from "potash" as it was first isolated from caustic potash, another term for potassium hydroxide. Thus, while they reference different substances, their linguistic roots are intertwined.

◉Potassium
A soft, silver-white, extremely reactive element that is an alkali metal, is essential to plant and animal cell functions, and occurs in nature only in compounds. It can be obtained by electrolysis of its hydroxide and is found in, or converted to, a wide variety of salts used especially in fertilizers and soaps. Atomic number 19; atomic weight 39.098; melting point 63.5°C; boiling point 759°C; specific gravity 0.86; valence 1. See Periodic Table.
