Potassium hydroxide

Potassium hydroxide has many different functions and uses.It is primarily used as an intermediate in industrial manufacturing processes, such as the manufacture of fertilisers, potassium carbonate or other potassium salts and organic chemicals.It is also used in the manufacture of detergents and in alkaline batteries.Small-scale uses include drain cleaning products, paint removers and degreasing agents.manufacture of liquid soap;mordant for wood;absorbing CO2;mercerizing cotton;paint and varnish removers;electroplating, photoengraving and lithography;printing inks;in analytical chemistry and in organic syntheses.Pharmaceutic aid (alkalizer).
Pure potassium hydroxide is a solid at room temperature, though it is often sold as a liquid. Potassium hydroxide is a strong alkaline substance that dissociates completely in water into the potassium ion (K+) and hydroxide ion (OH-). The dissolution in water generates heat, so a vigorous reaction can occur when potassium hydroxide is added to water. The vapor pressure of the substance is very low and the melting point is high. Potassium hydroxide solutions attack aluminium and its alloys under formation of hydrogen gas. It can be neutralised with acids (e.g. hydrochloric acid) giving the corresponding potassium salts of the acids, which are usually pH neutral and non-corrosive.
