Key Properties
Potassium hydroxide 40% solution (for analysis) is a concentrated aqueous preparation that serves as a highly effective base in various analytical procedures. This solution is notable for its high purity and is specifically formulated for laboratory use, ensuring reliable results in chemical analyses. Potassium hydroxide, commonly referred to as caustic potash, is a strong alkaline compound that readily dissociates in water to yield hydroxide ions, making it a powerful reagent in titrations and other chemical reactions. The solution is supplied in a ready-to-use form, facilitating ease of handling and application in laboratory settings.
Also known as Caustic Potash, KOH Solution.
