Product Description:
Used as a primary standard in acid-base titrations due to its high purity, stability, and well-defined acidic properties. It is especially valuable for standardizing alkaline solutions like sodium hydroxide. Commonly employed in analytical chemistry laboratories for calibration of pH meters because of its consistent and reproducible pH when dissolved in water. Also utilized in buffer solutions to maintain a stable pH environment, particularly in biological and chemical research. Its low hygroscopicity ensures accurate weighing and reliable results in quantitative analysis.
