Potassium Hydroxide (KOH) Explained

Potassium hydroxide (KOH) is an inorganic compound composed of potassium (K+), hydrogen (H+), and hydroxide (OH-) ions. It is typically available in solid form as white, deliquescent flakes or pellets. Similar to other alkalis, potassium hydroxide is highly soluble in water and generates an exothermic reaction upon mixing. It possesses strong alkaline properties and is highly corrosive, necessitating careful handling and proper safety precautions.

Fact number one

Of all the compounds in the hydroxide group, potassium hydroxide and sodium hydroxide are the most chemically similar.

Fact number two

Their chemical reactions, physical appearance in solid and liquid form and behaviour are closely matched, which allows them to stand in for one another in a number of uses.

Fact number three

The world consumes 700,000 to 800,000 tonnes of the compound every year.
