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.
Cabbage indicator stays the same color in water because water has a neutral pH, which does not cause the indicator to change its color. The pigment in cabbage indicator changes color in response to changes in the pH level of its environment, but since water has a pH level close to 7 (neutral), there is no significant change in color.
Slightly acidic, 5<pH<8 , because at pH above 8 it would have been purple
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.
its kind of orange and i think the ph of NaOH is 8-10................... double check though coz i tested this with red cabbage juice so i am not sure.................. \\\
I think it is used for meassuring the pH level or sumthing.

Which is more accurate- the pH paper or the red cabbage juice and why?
The pH of cabbage typically ranges from 6.0 to 7.0, making it slightly acidic to neutral. This pH can vary based on factors such as the type of cabbage and its growing conditions. When fermented, such as in sauerkraut, the pH can drop to around 4.0 due to the production of lactic acid.
Red cabbage can turn red when mixed with lemon juice due to a change in pH level. The anthocyanin pigments in red cabbage react to the acidity of lemon juice, causing the cabbage to turn red.
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.
Phenolphthalein is not naturally present in cabbage juice; however, cabbage juice can serve as a pH indicator due to the presence of anthocyanins, which change color based on acidity or alkalinity. When cabbage juice is mixed with a basic solution, it will typically turn a greenish-yellow color, while in acidic solutions, it may appear reddish-purple. If phenolphthalein is added to cabbage juice, it could alter the color response based on the pH level of the solution.

Calcium carbonate reacts with cabbage juice because the juice contains anthocyanins, which are pH-sensitive pigments. When calcium carbonate is added to cabbage juice, it reacts with the acids present in the juice, leading to a change in pH. This reaction can cause a color change in the juice, demonstrating the acid-base interaction. The presence of calcium carbonate neutralizes the acidity, resulting in a shift in the color of the cabbage juice, which can range from pink to green depending on the pH level.
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.
