What makes a good pH indicator?
Red Cabbage extract
Why is the universal indicator more useful than the red cabbage?
The universal indicator is better than the red cabbage indicator because the universal indicator has a wider range of pH that it can explain why a substance is acidic or basic. The red cabbage indicator only tests the substance if it is an acid or a base. Also, the universal indicators are made carefully and it is manufactured in a precise manner so the results are very reliable. Red cabbage indicators will vary in concentration which could cause errors to occur in determining the pH of a substance.
What is the PH level for cabbage?
93283.
What are examples of synthetic pH indicators?
Red Cabbage Juice can be used as an easy natural indicator. Bromothymol Blue is a common chemical pH indicator
What fruit and vegetable can you use as a pH indicator?

What is the main usage for red cabbage?
Red cabbage is also known as purple cabbage, red kraut, or blue kraut. Its leaves are dark red/purple, however the color of the leaves are affected by the pH value of the soil. Most commonly, red cabbage is used in cooking. It is often used for coleslaw.
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).
Define natural acid-base indicator?
Nature provides us with pH indicators in the form of plant pigments known as antocyanines, which change color over different pH ranges, depending on source. The indicators derived from red cabbage and red beet are two examples. Red cabbage juice will function over a wide pH range, from as low as pH 1 up to pH 12. The following is a pH color chart for red cabbage... pH 2=red, pH 4=purple, pH 6=violet, pH 8=blue, pH 10=blue-green, pH 12 = green-yellow.

Red Cabbage extract
What color does red cabbage juice change depending on the pH?
Cabbage contain Anthocyanins called Cyanidin. These are responsible for changing color with pH. Changing the pH affects the shape of the molecule which, in turn, changes its wavelength absorption.
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.
What is cabbage water?
I think it is used for meassuring the pH level or sumthing.
Why is red cabbage used as small pH indicator?
because....i don`t know!!
Red cabbage juice will turn green in what substance?
Any substance with a pH of 7.
How can you test for acids and bases?
by using phenolphthalein,litmus paper (red and blue),cabbage,tea,and PH paper or PH meter
Can an indicator an example is red cabbage juice test strengths of acids or bases?
Both of these can be used as an acid-base indicator. The juice from red cabbage will turn different colours over a wide range of pH, from pH 2 (very acidic) to pH 13 (very basic). Red beet will be blue or red depending if it's in acid or base.
