How do indicators work in acid base reactions?

Answer 1

Indicators a mostly the organic compound which change their functional groups' structures in different media by changing their colors. So, in acid base reactions acidic media is changed to basic or reverse happens, and this media causes the color change in indicators.

The video below shows an experiment using an indicator derived from boiling red cabbage. A pigment from the cabbage called anthocyanin is what causes all of the different colors you see.

Other common indicators include:
bromothymol blue
thymol blue
methyl orange
bromocresol green
methyl red
phenol red

Answer 2

Indicators work in acid-base reactions by undergoing a color change at different pH levels. They are typically weak acids or bases that exist in different forms with distinct colors in acidic and basic environments. The transition between these forms corresponds to a specific pH range, allowing indicators to signal the presence of acids or bases in a solution.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
