In science indicators are used for seeing weather a liquid is either a stong acid or alkailine or a week acid or aklaline or it can be neutral which is neither. You can check what it is by using a pH Scale.
In chemistry, an indicator can refer to one of a few things:
The most common usage is generally as a pH indicator. Synthetic indicators include:
Many plants or plant parts contain chemicals from the naturally-colored anthocyanin family of compounds. This would include litmus paper, which is a water-soluble mixture of different dyes extracted from lichens, especially Roccella tinctoria. They are red in acidic solutions and blue in basic. Extracting anthocyanins from red cabbage leaves or the skin of a lemon to form a crude acid-base indicator is a popular introductory chemistry demonstration.
Anthocyanins can be extracted from a multitude of colored plants or plant parts, including from leaves (red cabbage); flowers (geranium, poppy, or rose petals); berries (blueberries, blackcurrant); and stems (rhubarb).
A chemical indicator is a substance that indicates the absence or presence of certain compounds.
It is a material that changes color in the presence of an alkali and an acid. It is a safe way to find out if a chemical substance is basic or acidic.
An indicator is a chemical which will give a signal when a certain pH level is reached. Nearly always color, most indicators will change color, sometimes drastically, sometimes on a scale, on a certain range of pH. Most indicators work well either in an acidic or basic environment, but some are more universal.
Indicators are used to determine whether the solution is acidic, basic or neutral.
halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or basicity) of the solution can be determined visually.
Some indicators are: methyl orange, thymol blue, Congo red, bromcresol green, phenolphthalein, alizarine yellow R.

The six phase transitions in chemistry are melting, freezing, evaporating, condensing, sublimation, and deposition. These phase transitions are used to refer to how an element changes from one state to another.

The six indicators of water quality are temperature, pH level, dissolved oxygen, turbidity, nitrate levels, and phosphorus levels. These indicators help determine the health of aquatic ecosystems and the suitability of water for human consumption.
There are many different indicators in chemistry which can be blue. Some indicators indicate the presence of a species such as a metal ion, whereas others are pH sensitive. The exact meaning depends on the specific indicator used. For example, blue litmus paper indicates a basic solution.

Three of the areas of research that are affected by chemistry are organic, theoretical, and biochemistry. The other three are polymer science, surface and colloid chemistry, and analytical/environmental chemistry.
The six phase transitions in chemistry are melting, freezing, evaporating, condensing, sublimation, and deposition. These phase transitions are used to refer to how an element changes from one state to another.
It is structure indicators, process indicators and outcome indicators.
