An example of an indicator would be Phenol Red, or Universal Indicator. Depending on the pH range of the indicator and the pH range of the substrates you would use the appropriate indicator.
Internal indicators that are used in titration exist in the titration reaction as either a reactant or a product. External indicators is added to the reaction mixture, but does not exist in the reaction.
what is precipitation used in science?
Indicators used outside the titration flask are termed as external indicators. A very commonly used external indicator is potassium ferricyanide
because external indicators are weak acids or bases and alcohol itself being a weak acid will react with it if it is used in vessel with them..... hence the titration is done using external indicators....

fluorescein can be used as indicator in the titration of silver and chlorided

Precipitation Titrations are used for the analysis of halides and pseudo-halides for quantitative determination, as well as for some metal ions.
Definition of various terms used in Volumetric analysis ... Most of metallic halides are titrated by precipitation method.
Indicators are weak acid. Too much will alter the titre
an indicator used in reaction that involve precipitation is called absorbing indicator
Argenmetric process
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
