Mordant Yellow 1 pH indicator solution is widely used in analytical chemistry for determining the pH of solutions. It is particularly effective in titration experiments, where it helps identify the endpoint of acid-base reactions by changing color from yellow at pH 10.0 to brownish yellow at pH 12.0. This indicator is also employed in laboratory settings for monitoring pH changes in various chemical processes. Additionally, it finds application in educational demonstrations to visually illustrate pH transitions, making it a valuable tool for teaching fundamental chemistry concepts. Its stability and clear color change make it a reliable choice for precise pH measurements in research and industrial applications.
