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.
What is the chemical used to identify changes in pH?
They are called pH indicators.
What can indicators identify?

What will change color in the presence of an acid or a base?
pH indicators change the color depending upon acidity or basicity.
How are lichens used to make litmus paper?
The indicators in litmus are extracted from lichens; the color of litmus depends on the pH of the solution.
What is a hibiscus's preferred pH?

What can use to make pH scale indicator?

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.

Why doesn't turps react with pH indicators?
most pH indicators are polar, whereas turps is non-polar so it doesnt mix well
What will change color in the presence of an acid or a base?

What compound changes color when used to determine the pH of a substance?
There are a variety of indicators used to determine change in pH. Different indicators change during certain ranges of pH. For example, phenolphthalein turns from clear to pink in a basic solution (approximately 7.8 to 9). There are universal indicators that cover the whole pH scale.
Examples of plant indicators for measuring pH values?
a plant pH indicator is onion
