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.
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.
How can you tell if ink is a natural indicator?
A natural indicator will typically be a plant-based substance, such as beet juice or red cabbage extract. These natural indicators will change color in response to changes in pH, with colors like red, pink, purple, and blue being common. If the ink contains natural ingredients and changes color in response to acidic or basic conditions, it is likely a natural indicator.

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.
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 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!
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 test natural indicator?
with some poo
How tea is a natural indicator?
Tea is a natural indicator because it shows the pH of something on a scale however it is very basic as you will not get a full colour range.
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 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.
