Which is more accurate- the pH paper or the red cabbage juice and why?
The pH level of cabbage is typically around 6.0-7.5, making it slightly acidic to neutral.
Red cabbage contains a natural pigment called anthocyanin, which changes color based on the pH of its environment. In acidic conditions (pH below 7), red cabbage appears pink or red, while in neutral to alkaline conditions (pH above 7), it turns green or blue. This property makes red cabbage an excellent natural pH indicator. Typically, the pH of red cabbage itself is around 5 to 6, making it mildly acidic.
Water has a higher pH than cabbage juice. Better? I wish I know what cabbage juice's pH was but the stupid internet won't let me find it. Just gives me links to cabbage juice indicators. The lower the pH, the more acidic it is. 7 pH is pure water.
Slightly acidic, 5<pH<8 , because at pH above 8 it would have been purple
I think it is used for meassuring the pH level or sumthing.
Cabbage contains a pigment called anthocyanin that changes color based on pH levels. Lettuce does not contain this pigment, so it cannot be used as a pH indicator.
Cabbage chemistry help the environment by introducing a favorable pH to the soil.
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.
Cabbage is slightly alkaline with a pH level ranging from 6.5 to 6.9. When consumed, it can help maintain the body's pH balance by counteracting acidic foods.
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.
Red cabbage can be used as a pH indicator for a wide range of pH levels, showing different colors depending on the acidity or alkalinity of a substance. Similarly, beets can also be used as a pH indicator, turning different colors in acidic or basic solutions.
