Bleach turns yellow when mixed with red cabbage juice due to the chemical reaction between the bleach (sodium hypochlorite) and the pigments in the cabbage juice, primarily anthocyanins. These pigments are sensitive to pH changes and can change color in response to different chemical environments. When bleach is introduced, it alters the pH and oxidizes the anthocyanins, resulting in a yellow hue. This color change is a visual indication of the chemical transformation occurring in the mixture.

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.
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 turns cabbage juice red?
Cabbage juice turns red due to the presence of anthocyanins, which are natural pigments found in red cabbage. These pigments change color based on the pH of their environment; they appear red in acidic conditions and greenish-yellow in alkaline conditions. When the juice is mixed with acidic substances, such as vinegar or lemon juice, it produces a red hue.
What color does vinegar make when mixed with cabbage juice?
orange
What colour does vinegar change when mixed with red cabbage juice?
it will be purple
What color does citric acid change when mixed with cabbage juice?
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.
What happens red cabbage juice is mixed with baking soda?
When red cabbage juice is mixed with baking soda, a chemical reaction occurs. The baking soda is a base and reacts with the anthocyanins in the red cabbage juice, causing a color change. The mixture will turn blue or blue-green due to the change in pH.
What color does sprite turn when mixed with red cabbage juice?
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.
What vegetable turns red with lemon?
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.
What color does ammonia change when mixed with cabbage juice?
Basic colour of C.J. is purple blue
What color is red cabbage juice with epsom salts and ammonia?
Red cabbage juice is a natural pH indicator that changes color based on acidity or alkalinity. When mixed with Epsom salts (magnesium sulfate), the juice may remain a purplish hue, but when ammonia (which is alkaline) is added, the color shifts to a greenish-yellow. This color change occurs because the ammonia raises the pH, causing the anthocyanins in the cabbage to alter their structure and absorb light differently.
What does cabbage juice have to do with pH?
the color of the cabbage juice mixed with the chemicals shows where the chemicals would be placed on an pH scale. the lighter the chemical is with the cabbage juice, the more acidic. the darker, the more basic.
