Potassium hydroxide
Subordinate classification: chemical drug medication list of names
Abstract:
KeXingJia said KOH, a strong alkali chemical raw materials. Often used in producing potash (TV tube production of glass and glass), soft soap and detergent and pigments, electroplating, alkaline battery electrolyte, etc can be used. Solid potassium hydroxide crystallization, easy for white orthogonal ChaoXie and carbon dioxide. Insoluble in water, soluble in hot out alcohol and glycerol.

Solid potassium hydroxide crystallization, easy for white orthogonal ChaoXie and carbon dioxide. Insoluble in water, soluble in hot out alcohol and glycerol. Melting point 360.4 degrees Celsius. The chemical properties similar sodium hydroxide solution), (caustic soda in alkaline, can damage cells. Have 1, 2, 4 molecular water hydrate. Solid potassium hydroxide in water or steam heat producing inflammable substance, can make to combustion temperature, it should be stored in dry places. Contact the protective measures of potassium hydroxide with sodium hydroxide.
