Description

Application
In terms of application this solution is commonly used in analytical chemistry particularly in non-aqueous titrations. It is widely employed for the determination of acidic substances that are poorly soluble in water such as weak organic acids fatty acids and compounds in oils and fats. It is also used in industries like pharmaceuticals cosmetics and food analysis to measure acid values and ensure product quality.

Purpose
The purpose of preparing potassium hydroxide in isopropanol at a specific normality (0.1 N) is to obtain a precise and reliable titrant for quantitative analysis. The non-aqueous medium enhances the solubility of organic analytes and improves the accuracy

General Description
It is a standardized solution of Potassium hydroxide dissolved in Isopropanol with a normality of 0.1. It is a clear strongly basic solution where isopropanol acts as an organic solvent instead of water making it suitable for reactions involving non-aqueous systems. This solution is hygroscopic and must be stored carefully to avoid absorption of moisture and carbon dioxide from the air which can alter its concentration.
