Product Description:
Used as a pH indicator in analytical chemistry, particularly in acid-base titrations. It changes color depending on the pH of the solution, typically appearing yellow in acidic conditions and turning red or orange in alkaline environments. Commonly applied in laboratory settings to determine the endpoint of titrations involving weak acids or strong bases. Also utilized in educational experiments to demonstrate pH-dependent color changes. Suitable for use in aqueous solutions where a transition range between pH 10.0 and 12.0 is required.
