Key Properties
POTASSIUM HYDROXIDE 0.5M (0.5N) In Ethanol Standardized Solution is a certified solution used primarily for non-aqueous acid-base titrations. This solution contains potassium hydroxide (KOH) dissolved in ethanol (C2H5OH), providing a reliable and standardized base for various analytical applications. The solution is notable for its precise concentration, which is essential for accurate titration results. It is commonly utilized in laboratories for the determination of fatty acids and saponification values in oils and fats.
Also known as KOH solution in ethanol.
