Cabbage Juice

When you blow into a straw in red cabbage juice, the color will change to a shade of blue or green. This occurs because the carbon dioxide from your breath reacts with the anthocyanins in the red cabbage juice, which are pH indicators. The increase in acidity from the carbon dioxide leads to a shift in color.

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.

Cabbage juice may help in healing ulcers due to its high content of vitamins U (S-methylmethionine) and C, which have been associated with promoting healing in the gastrointestinal tract. Some studies suggest that cabbage juice can reduce inflammation and promote mucosal healing. However, while it may provide some benefits, it should not replace conventional medical treatment for ulcers. Always consult a healthcare professional for proper diagnosis and treatment.

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.

Car battery acid mixed with red cabbage juice turns a vibrant shade of pink or magenta due to the pH levels changing. So, if you're looking for a fun science experiment or a colorful way to test acidity, go ahead and mix those two together. Just be sure to wear gloves and goggles, because safety first, darling.

Because its not nearly as accurate as litmus. Its hard to judge the changes in colour and also it smells quite bad, is difficult to set up and is plainly just far much more hassle. As far as performance it works averagely and can be used in school labs etc where accuracy isn't such a big deal, but in science labs outside of this, you would need something stronger and more reliable

Beet or cabbage juice can be used as sources of certain vitamins including iron and vitamin B. These items can also be used to create a beef and cabbage stew.

contrary to popular belief it is not actually blood. Blood is almost all drained out at the slaughter.It is actually myoglobin mixed with water. This is why there is no red juice in white meat.

Red cabbage contain a pigment from the group of anthocyanins.
See the general structure of an anthocyanin at the link below.

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 a base mixed with Red Cabbage Juice will turn green.

no it reacts only with rainbow cabbage juice and not red

When adding tomato juice to cabbage juice, the cabbage juice turns redish

As tea ranges from mildly to strongly acidic, the cabbage juice should turn red or pinkish.

orange

Both of these can be used as an acid-base indicator. The juice from red cabbage will turn different colours over a wide range of pH, from pH 2 (very acidic) to pH 13 (very basic). Red beet will be blue or red depending if it's in acid or base.

It will turn a red color indercating that is has got acid in it

Neither one is better than the other. Man-made and natural pH indicators do virtually the same exact thing, just with different materials.

put small pieces of purple cabbage in hot water and stir it and leave it for 20 min and take only water.

if indicator turns substance red it is acidic ,if blue then basic if no change then neutral
