Can pH indicator give accurate pH reading for solution?
An accurate measurement is made with a pH-meter; pH-papers make only approximative determination.
What does red cabbage indicator do that other indicators don't?
Nothing, but red cabbage is a simple pH indicator at home (red in acidic solutions).
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
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.
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)
How do you make a pH indicator not using red cabbage?
A pH indicator can be made out of grape juice or beetroot or even eggplant. Grate 1/4 cup of beetroot or eggplant into 2 cup water, boil for 10 min and strain for the dark liquid, by the way grape juice could be used right out of carton. Add indicator to the substance that is being tested, it will be more red for pH of 2 and greener for pH of 12, and test for better knowledge of all colors that pH indicator can turn.
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.
