Which is more accurate the pH paper or the red cabbage juice and why?
Which is more accurate- the pH paper or the red cabbage juice and why?
What happens when you add water to cabbage juice?
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.
What color does cabbage juice turn if you add base to it?
Cabbage juice is a natural pH indicator that changes color when mixed with acids or bases. When a base is added to cabbage juice, it typically turns a greenish-yellow color. This color change occurs because the pigments in the cabbage juice, known as anthocyanins, react to the pH change.
Why does calcium carbonate react when put in cabbage juice?
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.
Does cabbage juice change alum?
Yes, cabbage juice can change color when mixed with alum due to the pH changes that occur. Cabbage juice contains anthocyanins, which are pH-sensitive pigments. When alum, a basic compound, is added, it can alter the acidity of the solution, causing the cabbage juice to shift from its original color to shades of green or blue, depending on the concentration. This makes it a useful natural indicator for pH levels.
Why might red cabbage juice be a different color in vinegar than in baking soda?
Red cabbage juice is a natural pH indicator that changes color based on the acidity or alkalinity of the solution. In vinegar, which is acidic, the cabbage juice turns red or pink. In baking soda, which is alkaline, the cabbage juice turns blue or green. This color change is due to the interaction between the pigment molecules in the cabbage juice and the different pH levels of the solutions.
Is phenolphthalein in cabbage juice?
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.
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.
What would happen if you added cabbage juice indicator to dishwasher detergent?
If the pH of a detergent is usyally greater then 7 the juice of red cabbage become blue to green in this solution.
What is the pH value of red cabbage?
Slightly acidic, 5<pH<8 , because at pH above 8 it would have been purple
Red cabbage juice will turn green in what substance?
Any substance with a pH of 7.
Why does cabbage juice change pink in aspirin?
Cabbage juice contains a pH indicator called anthocyanin, which changes color in response to the acidity or alkalinity of a substance. When cabbage juice is mixed with aspirin, which is acidic, the anthocyanin reacts to the pH change, resulting in a pink color. This color change is a visual representation of the acidic nature of aspirin, demonstrating how natural indicators can be used to gauge pH levels.
