What are the functions of indicators?

Answer 1

Indicator species are a useful management tool, and can help us delineate an ecoregion, indicate the status of an environmental condition, find a disease outbreak, or monitor pollution or climate change. In one sense, they can be used as an "early warning system" by biologists and conservation managers. Indicator species must also be accompanied by a thorough study of what is being indicated, what is really correlated, and how this one species fits into the rest of ecosystem.

Answer 2

A chemical indicator changes an observable characteristic based on a chemical reaction with an unknown.

For example a pH indicator, like the anthocyanins in red cabbage juice, might appear red in acid solutions and blue in basic solutions. Methylene blue has a rather different use, as it is a redox indicator.

Answer 3

Indicator is a process which is used to find out the substanceis acid,base and salt.

example: litmus paper and termuric both are natural indicator.

example of artificial indicator: mithyl orange and phenolphtaceil

Answer 4

Indicators are used to monitor, assess, and communicate progress towards achieving specific goals or objectives. They help track trends, provide early warnings of potential issues, and inform decision-making. Overall, indicators serve as tools for measuring, comparing, and evaluating performance or outcomes.

Answer 5

I assume this refers to a pH indicator, such as indicator paper that you dip into a solution. This tells you the pH of the solution, i.e. whether it is an acid, a base, or neutral.

Answer 6

indicators indicate when the reaction is complete

Answer 7

To react and tell the user something about the situation in which the indicator is used.

Answer 8

A indicator is a substance that undergoes change when conditions in the solution change. It helps when creating experiments to get more accurate results.
