Product Description:
Used as a dual-color pH indicator in analytical chemistry, this solution is particularly effective in titration experiments where a wide or distinct pH transition range is required. It combines the properties of phenolphthalein and nile blue, allowing for a clear visual shift between acidic and basic environments. The color changes from blue (acidic) to violet and finally to pink (basic), making it useful for detecting endpoint transitions in weak acid-strong base titrations. It is also employed in educational labs to demonstrate multi-stage pH indicators due to its clear and gradual color progression. Additionally, it can be used in environmental testing and quality control processes where precise pH monitoring is needed.
