Used in analytical chemistry to maintain a stable pH during titrations and other pH-sensitive procedures. Commonly applied in complexometric titrations involving EDTA, where consistent pH is critical for accurate metal ion determination. Also utilized in buffer solutions for laboratory sample preparation, especially in environmental and water quality testing. Suitable for use in biological and biochemical research to control pH in assays and enzyme reactions. Frequently employed in industrial processes requiring pH stabilization, such as in textile treatment and metal plating.
