Potassium hydroxide, also known as caustic potash or potash lye, is an inorganic compound with the formula KOH.
Manufacturers commonly produce potassium hydroxide by the electrolysis of a potassium chloride (KCl) solution. Potassium hydroxide is an odorless, clear liquid solution. KOH is a strong corrosive base because it breaks up in water into K and OH ions.
Caustic potash has high thermal stability and a relatively low melting point. Companies often metal-cast potassium hydroxide as pellets or rods since these forms have a low surface area.
When combined with an acid (neutralization reaction), potassium hydroxide will react violently and produce water, salt, and heat (heat of neutralization).
When in contact with many common metals (aluminum, tin, and zinc), potassium hydroxide reacts to produce flammable and potentially explosive hydrogen gas.
Northstar’s Potassium Hydroxide Products
Northstar Chemical offers liquid potassium hydroxide commonly as a 50% or 45% solution but can provide several dilutions from there. We also provide many custom blends with KOH.
Northstar offers potassium hydroxide in bulk and mini-bulk.
