- Potassium hydroxide is an inorganic
compound with the formula KOH, commonly called caustic potash.
- Along with sodium hydroxide (NaOH), this
colorless solid is a prototypical strong base. It has many
industrial and niche applications.
- Most applications exploit its reactivity
toward acids and its corrosive nature.
- In 2005, an estimated 700,000 to 800,000
tonnes were produced. Approximately 100
times more NaOH than KOH is produced annually. KOH is noteworthy as
the precursor to most soft and liquid soaps as well as numerous
potassium-containing chemicals.
- Historically KOH was made by boiling a
solution of potassium carbonate (potash) with calcium hydroxide
(slaked lime), leading to a metathesis reaction which
caused calcium carbonate to precipitate, leaving potassium hydroxide
in solution.
- Many potassium salts are prepared by
neutralization reactions involving KOH. The potassium salts of
carbonate, cyanide, permanganate, phosphate, and various silicates
are prepared by treating either the oxides or the acids with KOH.
- The high solubility of potassium phosphate
is desirable in fertilizers.
- The saponification of fats with KOH is
used to prepare the corresponding "potassium soaps", which are
softer than the more common sodium hydroxide-derived soaps. Because
of their softness and greater solubility, potassium soaps require
less water to liquefy, and can thus contain more cleaning agent than
liquefied sodium soaps.
- Like sodium hydroxide, potassium hydroxide
attracts numerous specialized applications, virtually all of which
rely on its properties as a strong chemical base with its consequent
ability to degrade many materials.
- In agriculture , potassium hydroxide is
used to correct the pH of acidic soils. It can also be used as a
fungicide or even an herbicide .
- Other uses include in veterinary medicine
in disbudding calves horns and to dissolve scales and hair; in human
medicine , to diagnose fungal infections and as a wart and cuticle
solvent; manufacture of cleansers.
- Potassium hydroxide is used in the
production of agricultural-grade fertilizers. These fertilizers can
be used as a source of potassium (one of three major plant foods)
for crops that are sensitive to chloride ions.
- Potassium soaps include those made from
coconut oil fatty acid, vegetable oil, tall oil and toluene sulfonic
acid.
