Potassium Hydroxide, Caustic potash
white flakes. It is one of the strongest alkalis. react quickly
with moisture liberating heat.
3.Applications:potassium hydroxide is used to maintain or increase pH. Increasing
pH with potassium hydroxide precipitates magnesium (Mg2+) and
suppresses calcium (Ca2+) in highhardness waters like seawater,
reduces corrosion, and neutralizes acid gases such as carbon
dioxide (CO2) and hydrogen sulfide (H2S). It is used instead of
caustic soda in inhibitive waterbase fluids and drillin fluids to
reduce the sodium ion content and avoid dispersion of clays.
1. Widely available and economical source of hydroxyl ions to
2. Concentrated chemical that is very effective at small treatment
3. Increases pH, which reduces corrosion of steel exposed to
4. Can be used in most waterbase drilling fluids.
