Other types of indicators include bromothymol, phenolphthalein and phenolphthalein. These indicators are used to observe the reaction between an acid and a base and they can be useful in determining the precise equivalent point of the titration.<br><br>Indicators function by using a molecular acid form (HIn) and an Ionic Acid form (HiN). The chemical equilibrium between the two forms depends on pH, so adding hydrogen to the equation causes it to shift towards the molecular form. This results in the characteristic color of the indicator. The equilibrium shifts to the right away from the molecular base, and towards the conjugate acid when adding base. This is the reason for the distinctive color of the indicator.<br><br>Indicators are commonly used in acid-base titrations however, they can be employed in other types of titrations, like the redox and titrations. Redox titrations can be a bit more complicated, however the principles are the same as those for acid-base titrations. In a redox test the indicator is mixed with some acid or base in order to be titrated. If the indicator's color changes in reaction with the titrant, it signifies that the process has reached its conclusion. The indicator is then removed from the flask and washed off to remove any remaining titrant.
