pH indicator works as the range by alkalinity wether it's basic or acidic. Indicator properties are often found naturally in plants (eg. litmus). pH indicators are often just refined versions of various natural plant chemicals or synthesized versions of them.

∙ 9y agoA pH indicator works due to the interaction it has with the hydrogen ions in a substance, which is what determines how alkaline or acidic the substance is. These substances help measure the pH value via the different colors they take at different pH levels.

How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
What is the pH indicator used in the citrate test?
The indicator is bromothymol blue.
What is it called when a substance changes color in response to pH?
This is a pH indicator.
PH or acidity which is better indicator?
The acidity range is a part of the pH scale.
Could universal indicator be used to identify a liquid as being pure water?
A pH indicator is used only to measure the pH of the solution.
A compound that can reversibly change color depending on conditions such as pH?
They are comonly known as "indicators" as the color change is useful for indicating what the pH of a solution is.
What fruit and vegetable can you use as a pH indicator?
cabbage juice is a natural pH indicator
Why is a universal indicator more useful than litmus paper for measuring pH in some applications?
this is because it is more specific(Y):)
What changes color on pH?
a pH indicator
How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
What property of phenolphthalein makes it useful indicator for acid-base titrations having equivalence points in the pH range from 7-9?
The colorless solution change to a pink solution (at the pH mentioned).
Can an indicator provide an exact pH?
An indicator can provide exact pH if you are using the neutralization titration. Paper strip pH indicator are not an exact measurement but a high, medium, and low indication of acids and bases.
What creteria is used for chosing an indicator in acid base titration?
pH range of indicator should be in the rapid pH gradient.
How we measure the pH of body fluids with pH paper?
ph-indicator strips (colorpHast)
What is the pH indicator used in the citrate test?
The indicator is bromothymol blue.
What kind of indicators are used in precipitation titration?
An example of an indicator would be Phenol Red, or Universal Indicator. Depending on the pH range of the indicator and the pH range of the substrates you would use the appropriate indicator.
The pH number is an indicator for?
Hardness
