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.
at first it will turn purple then it will turn pink
When adding tomato juice to cabbage juice, the cabbage juice turns redish
When sodium hydroxide is added to red cabbage juice, the cabbage juice will change color. The cabbage indicator will turn from red/pink to blue/purple because sodium hydroxide is a strong base, causing a shift in the pH of the solution. This color change is due to the anthocyanin molecules in the red cabbage juice reacting with the change in acidity.
pink
Red cabbage juice will turn pink when an acid is added to it. Due to the acids in a carbonated drink, 7up till turn the juice a pink colour.
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.
IODINE
Citric acid mixed with cabbage juice turns the solution red/pink in color. This is due to the natural pigment in red cabbage, anthocyanin, which changes color in response to changes in pH levels.
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.
It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.
It will turn either blue or green, both a hue of blue. The reason of this is that Red Cabbage Juice is an indicator, which is used to see wether an object or chemical is an acid or a base. If the object is an acid it will turn a hue of pink, and if it is a base, it will turn a hue of blue. Which is why baking soda mixed with Red Cabbage Juice will turn blue or green.
When Sprite is mixed with red cabbage juice, it typically turns a purplish color. This occurs because red cabbage juice contains anthocyanins, which change color depending on the pH level of the mixture. Sprite, being acidic, can result in a color shift to a more vibrant purple or even pink hue.
