Two examples are phenolphthaleine and methyl orange.

Indicators
to indicate something
As a matter of fact, anthills are indicators of groundwater. There is a very high possibility that you will find underground water in places where you will find anthills.
Universal indicators can be mixed with different substances. Universal indicators usually contain water, salt, propan-1-ol, sodium hydroxide, monosodium, phenolphthalein sodium salt, methyl red, bromothymol blue, and thymol blue monosodium salt
your guess is as good as mines.lol
The color of indicators is changed in acidic solutions.For example thymol blue is red at low pH.
For example the red cabbage juice.
There are two main types of indicators used in titration: color indicators and pH indicators. Color indicators change color at specific pH ranges to indicate the endpoint of the titration, while pH indicators change color based on the pH of the solution.
There are two indicators in measuring the effectiveness of global trade. One is by managing the national credit card, and another is by balancing of payments.
Observing social indicators can help you understand a society's success. For example, indicators like high education level, low unemployment, and high average income can reveal that a society is well-run.
There are two types. Those are acidic or basic.

Two indicators are often used in titration to provide a more accurate measurement of the endpoint of the reaction. This is especially important when the color change of a single indicator is not sharp enough to clearly indicate when the reaction is complete. By using two indicators with different color changes at slightly different pH levels, the endpoint can be more precisely determined.
