Product Description:
Ethyl orange is primarily used as a pH indicator in various analytical and laboratory applications. It is particularly effective in titration processes to determine the acidity or alkalinity of a solution. The compound changes color at a pH range of 3.1 to 4.4, transitioning from red in acidic conditions to yellow in basic conditions, making it useful for identifying pH shifts in chemical reactions. Additionally, ethyl orange is employed in dyeing and staining procedures in biological and histological studies, where it helps to differentiate cellular structures under microscopic examination. Its stability and distinct color change properties make it a reliable tool in both educational and research settings.
