During Titration the Colored Indicator Is Added?

Indicator: A substance that changes color in response to a chemical change. An acid–base indicator (e.g., phenolphthalein) changes color depending on the pH. ... A drop of indicator solution is added to the titration at the beginning; the endpoint has been reached when the color changes.

What happens during titration?

In a titration, a solution of known concentration (the titrant) is added to a solution of the substance being studied (the analyte). In an acid-base titration, the titrant is a strong base or a strong acid, and the analyte is an acid or a base, respectively.

Why indicator is added in titration?

The role of indicator in titration is to detect the endpoint of the titration. When the colour of the solution changes, it indicates that the concentration of the chemical specie has reached a critical range. This change in colour is possible with the help of indicators.
