What component in some flowers makes a good pH indicator?
The component in some flowers that makes a good pH indicator is the pigment called Anthocyanin
What fruit and vegetable can you use as a pH indicator?
cabbage juice is a natural pH indicator
What changes color on pH?
a pH indicator
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.
How we measure the pH of body fluids with pH paper?
ph-indicator strips (colorpHast)

Why is red cabbage indicator not a good experiment to measure buffering capacity?
A buffer absorbs or releases excess hydrogen ions, making the solution hold at a steady pH. Since red cabbage indicator makes a good pH indicator, it has a neutral pH. any amount of acids or bases added would change the pH of the red cabbage juices. If it made a good buffer, it would not make a good pH indicator.
Where can one purchase pH indicator paper?
A person can purchase pH indicator paper at a variety of places. Convenience stores or science warehouses are good places to look. Also online retailers will normally have an abundance of brands and types of pH indicator paper to sell.

How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
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
