Key Properties
POTASSIUM HYDROXIDE 0.5M (0.5N) Standardized Solution is a clear, colorless liquid that serves as a certified standardized solution for volumetric analysis. This solution is prepared from high-purity potassium hydroxide and is designed for use in titrations and other analytical procedures requiring a precise concentration of base. The solution is notable for its consistent quality and reliability in laboratory settings, making it an essential reagent for chemists and researchers. It is particularly useful in acid-base titrations, where accurate measurements are critical for determining the concentration of unknown solutions.
Also known as KOH solution, Caustic potash solution.

The solution is a clear, colorless liquid with a density of 1.023 g/mL. It has a boiling point of approximately 1320 °C (decomposes) and a melting point of -2 °C. Potassium hydroxide is highly soluble in water, with solubility exceeding 1000 g/L at 20 °C. The solution has a pH value of approximately 13, indicating its strong basicity. It is important to note that the solution is hygroscopic, absorbing moisture from the air, which can affect its concentration over time.
