Potassium hydroxide

Like sodium hydroxide, potassium hydroxide is an ionic compound - take my online class . The compound is highly soluble in water.

Its aqueous solution, potassium hydroxide, has similar properties to sodium hydroxide and is also called caustic potash because of its highly corrosive effect on the skin and eyes. In the past, potassium hydroxide was produced by reacting potash (potassium carbonate) with slaked lime (calcium hydroxide):

K2CO3 + Ca(OH)2 → CaCO3 + 2 KOH

Today, potash lye is produced similarly to sodium hydroxide by the chlorine-alkali electrolysis of potassium chloride (KCl) solution - solve chemistry problems . In contrast to sodium chloride, which occurs in the corresponding rock salt deposits with contents of over 99 %, the content of potassium chloride in the potash salt deposits is only 10 to 40 %. The main accompanying salts are sodium chloride and magnesium salts. These have to be separated from the potassium chloride in a complex process. As a result, potassium chloride has a much higher raw material price than sodium chloride. Consequently, potassium hydroxide is also considerably more expensive than sodium hydroxide and is therefore produced in smaller quantities.

Potassium hydroxide is used as a drying and absorption agent, in the production of soft soaps (soft soaps), as water-softening potassium phosphates for liquid detergents, in dye syntheses, in the development of films and in the production of other potassium compounds - pay someone to do my homework . Diluted potash lye is used in medicine for external cauterisation.
