Caustic potash / Potassium hydroxide / KOH 3 %
The 3% potassium hydroxide solution is a weakly concentrated alkaline solution used in various areas of the laboratory and industry. In microbiology, it can be used to distinguish yeasts and filamentous fungi by soaking samples in the solution and then examining them microscopically. The low concentration allows for gentle separation of organisms.
In the chemical industry, 3% potassium hydroxide is used to manufacture mild soaps, detergents and other products that require a weak alkaline reaction. In the textile industry, it can be used to remove grease and dirt, while in the food industry it is used to regulate pH and as a preservative.
In the laboratory, 3% potash lye is used as an etchant to remove proteins and grease from glassware or to neutralize acids. In industry, it is used in anisotropic etching of silicon and as an electrolyte. In addition, potassium hydroxide is used as an etching additive in metallography to make certain structures in metals visible. The 3% concentration provides a milder etching reaction than higher concentrations.
