natural indicators are cheap, while universal indicators are hard to obtain.
Common flowers that contain acid-base indicators include geraniums, hydrangeas, morning glories, poppies, tulips, violets, petunias, pansies, roses, and hibiscus flowers, among many others.
Some natural indicators include red cabbage, turmeric, and blueberries. These indicators change color in the presence of acids and bases due to their chemical properties. For example, red cabbage contains a pigment that changes from red in acids to green/blue in bases.
Examples of synthetic pH indicators include phenolphthalein, bromothymol blue, and methyl orange. These indicators change color in response to changes in pH, making them useful for visualizing acidity or alkalinity in solutions.
Natural indicators like red cabbage juice and turmeric can be used to detect basic solutions. These indicators change color in the presence of bases, turning blue or green for red cabbage juice and yellow for turmeric, indicating the basic nature of the solution.
The natural indicators are blackberry and many other bright-coloured flowers make good natural indicators

with some poo
A natural indicator is a solution that changes colour at different pH levels, however these indicators are dissimialr to common indicators such as phenolphtalein as natural indicator solutions are dirived from chemicals from oragnic materials such as carrots, berries and beetroot
Universal indicators are typically more effective than natural indicators like red cabbage or beetroot juice because they provide a continuous range of color changes across the pH spectrum, allowing for precise pH measurements. In contrast, natural indicators often show limited color variations and may only indicate specific pH ranges, making them less reliable for accurate assessments. Additionally, universal indicators are usually standardized and more consistent in their responses, while the color changes in natural indicators can be influenced by factors such as temperature and light.
i know only litmus paper:l
For example the red cabbage juice.
The rise in condom prices
natural indicators can be used to detect whether a given substance is an acid or base.It can be easily available in our homes too. And you can prepare it too.They do not have harmful affects .so they should be used instead of chemical indicator which may some time be harmful.
Common flowers that contain acid-base indicators include geraniums, hydrangeas, morning glories, poppies, tulips, violets, petunias, pansies, roses, and hibiscus flowers, among many others.
Examples: turmeric, methyl red, bromocresol green.
natural indicator indicate whether a substance is acidic or basic.these indicators occur naturally such as lichen.
