Potassium Hydroxide Formula

It is quite important to learn the potassium hydroxide formula as this chemical compound is one of the important inorganic strong bases having a wide number of applications both industrially and commercially. For example, it is used in the preparation of potassium salts, fertilizers, cleaning agents and refining petrol. Further, potassium hydroxide is basically a white solid which is highly hygroscopic. It is also sometimes called caustic potash or potassium hydrate.

Potassium Hydroxide Chemical Formula

Potassium hydroxide has the formula written as KOH. If we break it down, hydroxide (OH) has one hydrogen and one oxygen atom with a charge of 1. Whereas potassium (K+) which is an alkali metal has a charge of +1. Therefore the equation is balanced with the charges falling into an equal ratio.
