Chemical | Potassium Hydroxide - Refractometric Determination

Potassium hydroxide (KOH) is a strong base commonly used in various industrial processes, including chemical manufacturing, soaps and detergents, pharmaceuticals, and electrolyte solutions. Precise monitoring of KOH concentration is crucial to ensure process efficiency, product quality, and safety. Refractometry, based on the principle of refractive index measurement, is a non-destructive and rapid technique widely adopted for concentration determination in numerous industries.
This application report presents a comprehensive study on the measurement of potassium hydroxide (KOH) concentration using an Abbemat refractometer from Anton Paar. Refractometry is a widely employed method for determining the concentration of dissolved substances in solutions based on their refractive index. By utilizing an Anton Paar refractometer, we demonstrate the accurate and efficient determination of KOH concentration across various sample compositions and concentrations. The report discusses the methodology, instrumentation, experimental results, and highlights the advantages of using refractometry for KOH concentration analysis compared to titration.
