1. pluck 10-12 full hibiscus flowers
2. remove the sepals stigma so as to remain only with the petals
3. boil the petals in minimum water so the color leaches out or crush the petals in surgical spirit.
4. filter the solution
5. your indicator is ready

How indicators works?
pH indicators change their color according to the pH of a solution.
How are pH indicators classified?
pH indicators are classified based on the pH range over which they change color. They can be classified as either acidic, basic, or universal indicators. Acidic indicators change color in acidic solutions, basic indicators change color in basic solutions, and universal indicators change color over a wide pH range.
What is gumamela indicator?
Gumamela (Hibiscus) plants can be used as pH indicators. The flowers change color depending on the pH of the solution they are placed in, making them useful in determining acidity or alkalinity levels. For example, a red gumamela flower may turn violet in acidic solutions and green in alkaline solutions.
What can indicators identify?
Indicators are used frequently for testing pH; but many other indicators exist for other compounds or ions.
What will change color in the presence of an acid or a base?
pH indicators change the color depending upon acidity or basicity.
What is a hibiscus's preferred pH?
your pH
Why can't a single indicator be used to tell the pH of a solution?
A single indicator cannot be used to accurately determine the pH of a solution because indicators change color over a range of pH values rather than at a specific pH. Different indicators have varying color changes at different pH ranges, so using multiple indicators or pH meters provides a more precise measure of the pH of a solution.
What can use to make pH scale indicator?
Indicators are substances sensitive to different ranges of pH.
How indicators works?
pH indicators change their color according to the pH of a solution.
How many types of indictors are used in titration?
There are two main types of indicators used in titration: color indicators and pH indicators. Color indicators change color at specific pH ranges to indicate the endpoint of the titration, while pH indicators change color based on the pH of the solution.
How are pH indicators classified?
pH indicators are classified based on the pH range over which they change color. They can be classified as either acidic, basic, or universal indicators. Acidic indicators change color in acidic solutions, basic indicators change color in basic solutions, and universal indicators change color over a wide pH range.
Which property of a substance can be determined using a pH indicator?
The acidity or alkalinity of a substance can be determined using a pH indicator. pH indicators change color depending on the pH of a solution, allowing for the determination of whether the substance is acidic, neutral, or basic.
What are two ways scientists can measure pH?
Sorry, but there is only one solution. However, there are two ways to make these solutions. First you find the pH of either using litmus paper taht either turns red or blue indicating an acid or a base. Secondly, you can make your own natural pH indicator using red cabbage or blueberry. [[User:Bowler225|Bowler225]] 16:41, 18 Mar 2009 (UTC) There are many indicators. They change color at set pHs, which is known as the "transition range." Common indicators are Bromothymol Blue, Bromocresol Blue, Phenolphthalein and Methyl Orange.
What is acid-base indicators?
These indicators change the color depending on the pH of the solution.
What is gumamela indicator?
Gumamela (Hibiscus) plants can be used as pH indicators. The flowers change color depending on the pH of the solution they are placed in, making them useful in determining acidity or alkalinity levels. For example, a red gumamela flower may turn violet in acidic solutions and green in alkaline solutions.

Why doesn't turps react with pH indicators?
most pH indicators are polar, whereas turps is non-polar so it doesnt mix well
