How does a strawberry act as a natural indicator?
A strawberry can act as a natural indicator due to its pigment, anthocyanin, which changes color in the presence of acids and bases. When exposed to an acid, the anthocyanin in strawberries turns red, and when exposed to a base, it turns green. This color change can be used to determine the pH of a solution.
How does a flavin pigment molecule work with a pH indicator?
Flavin pigment molecule can interact with a pH indicator by changing its color based on the pH of the solution. The flavin pigment undergoes a chemical reaction with the pH indicator, leading to a change in its absorption spectrum or structure, resulting in a color change that can be used to determine the pH of the solution.
How do we extract an indicator from a natural plant?
To extract an indicator from a natural plant, one typically begins by selecting a plant known for its pigment properties, such as red cabbage or hibiscus. The plant material is then chopped and boiled in water to release the pigments into the solution. After straining out the solid plant matter, the resulting liquid can be used as a pH indicator, changing color in response to different acidity or alkalinity levels. This process can be further refined by concentrating the extract or adjusting its pH for specific applications.
What is meant by internal indicator?
Sometimes one of the reactants in a titration act as an indicator; this is an internal indicator. An example is the volumetric technique of permanganometry.
Is shoe flower a natural indicator?
Yes, shoe flower (hibiscus) is a natural indicator due to the pigments present in its petals. The petals can change color based on the pH of the solution it is in, making it a useful tool for pH testing in certain applications.

What is the natural indicator in a carnation?
The natural indicator in a carnation is anthocyanin, a pigment found in the flower's petals. This pigment changes color in response to pH levels; for example, it appears pink in neutral conditions and can turn blue or purple in more alkaline environments. This property makes carnations useful for demonstrating pH changes in educational settings.

Why can cabbage but not lettuce be used to create a pH indicator?
Cabbage contains a pigment called anthocyanin that changes color based on pH levels. Lettuce does not contain this pigment, so it cannot be used as a pH indicator.
How you can make a natural indicator?
You can use brightly coloured berries, flower petals and vegetables to make a natural indicator. The first thing you need to do is crush all your plant pieces using a pestle and mortar. Then you must add a little bit of methylated spirit. After that, keep on crushing until all the colour has come out. Then seperate the liquid from the plant remains using a pipette. Now you have a natural indicator. Hope this helped!
Is litmus a natural indicator?
litmus is a natural indicator because it is obtained from a natural source e.g. lichens mainly roccella tinctoria.it is not synthesized in the laboratory.
How does natural pigment influence the colour choice?
Natural hair pigments have a large influence on someone's natural hair color. The pigment is influenced by genetics and the parent's DNA shapes that.

How do you make an indicator from onions?
To make an indicator from onions, chop red onions and boil them in water for about 30 minutes to extract the pigment. Once cooled, strain the liquid to obtain a purple onion juice, which can act as a pH indicator. This juice changes color in response to different pH levels: it turns red in acidic solutions, purple in neutral solutions, and greenish-yellow in basic solutions. Store the indicator in a sealed container for future use.

What component in some flowers makes a good pH indicator?
Anthocyanins are the components found in some flowers that act as a good pH indicator. They change color in response to changes in pH levels, making them useful for determining whether a solution is acidic or basic. Examples of flowers containing anthocyanins include hydrangeas and red cabbage.
