WebThe difference between an External indicator and an Internal indicator is as follows, When a chemical species is externally added to act as an indicator is called an external indicator. When one of the reactants is capable to behave as an indicator, is known as an internal indicator. External indicator generally used in the acid-base titrations. WebTitration. Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change. The solution called the titrant must satisfy the necessary requirements to be a primary or ...
