The color remain red because vinegar is an acidic solution.
it will be purple
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.
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.
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.
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.
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.
Basic colour of C.J. is purple blue
When lemon juice is mixed with vinegar, it does not change color significantly. Lemon juice is already acidic and adding vinegar, which is also acidic, will not produce a significant color change.
Cabbage juice contains anthocyanins, which are pH indicators. When mixed with sodium hydroxide, a strong base, the color of cabbage juice changes to a greenish-yellow hue. This color shift occurs because the anthocyanins are sensitive to pH changes and react accordingly in alkaline conditions.
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.
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.
