Acid Alkali Indicators or pH Indicators
An acid-alkali indicator or pH indicator is a coloring agent which changes color to display whether an aqueous solution reacts as an acid or an alkali. In contrast to pH-indicator strips or indicator papers, which are mainly used to find the current pH value, the main use of pH indicators in laboratory applications is for the quantitative definition of the acid or alkali content of a solution (end-point indication/titration). When used as a rapid end-point indicator of an acid-base titration, the indicator shows a different color at the equivalence point compared to before it. This allows the user to visually recognize the end-point of the titration.
We offer you a clever and convenient tool that helps you quickly find the right pH indicator for your particular application. You simply need to enter the pH value required and you will immediately receive an overview of the suitable indicators, along with color information, transition intervals and other useful product information.
