An indicator is used in titrations to determine the endpoint experimentally and visually. Indicators change their color at the endpoint (or near the endpoint) so that the human eye can detect the change. The change in color occurs either due to a redox reaction or an acid-base ...
An acid turns the indicator litmus to what color? What is the color of a phenolphthalein indicator in an acidic solution? 1. A substance with a pH of 9 is considered {Blank}. \\ 2. If red litmus paper is used to test the substance it would turn what color? \\ a. ...
To determine the color of the China Rose Indicator when added to an acid, we can follow these steps:1. Understanding China Rose Indicator: - China Rose Indicator is derived from the petals of the China Rose flower. When the
An indicator, like phenolphthalein, is added into the unknown concentration. When the solution changes color (such as colorless to pink), the titration or neutralization point has been reached, and the unknown concentration may be calculated.

Eriochrome Black Tis a complexometric indicator that is used in complexometric titrations, e.g. in the water hardness determination process. It is an azo dye. What is the use of phenolphthalein? Phenolphthalein is often used asan indicator in acid–base titrations. For this application, it turns...
Litmus tests are used to determine whether a liquid is acidic or alkaline, that is, whether it has thecharacteristics of an acid or base. These tests are done by dipping strips of colored paper called litmus paper into the liquid in question and observing how the paper changes color. There...
The second common method is color-indicating titration, in which a pH indicator should be used, such as phenolphthalein. A burette is used to add the titrant to the sample where the permeant color change of the solution gives the endpoint of the solution, which indicates the total acid conten...
