Red cabbage powder is a natural acid-base indicator. It contains a compound that changes color when exposed to varying concentrations of hydrogen and hydroxide ions. When citric acid and water are added to the powder, the hydrogen ions from the acid interact with a chemical in the red cabbage powder, giving it a purple color.
Red cabbage contains a pigment molecule called anthocyanin that changes color depending on the pH of its environment. When citric acid is added, it lowers the pH of the solution, causing the molecule to change from a blue color to a purple one.
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.
Carbon dioxide gas is given off when the indigestion powder containing sodium hydrogen carbonate and citric acid is added to water. This reaction produces effervescence and helps relieve indigestion symptoms by neutralizing excess stomach acid.
An acid will turn the red cabbage indicator red, pink, or magenta in color. This change occurs because the anthocyanin pigments in the cabbage react with the acidic solution, causing a color change.
When citric acid is added, or any acid for that matter, the pH of a substance will decrease. This is because since acids have a low pH they will decrease the pH of other substances when added to it.
Citric acid can dissolve in water. When citric acid is added to water, it dissociates into ions, increasing its solubility in the water.
Base turn red cabbage solution to blue-ish purple
When adding tomato juice to cabbage juice, the cabbage juice turns redish
Citric acid is added for tartness.
Carbon dioxide gas is given off when the indigestion powder containing sodium hydrogen carbonate and citric acid is added to water. This reaction produces effervescence and helps relieve indigestion symptoms by neutralizing excess stomach acid.
Citric acid is added to juice drink preparations to enhance the flavor of the juice by providing a tart and tangy taste. It also acts as a natural preservative, helping to extend the shelf life of the juice by inhibiting the growth of bacteria and mold. Additionally, citric acid helps to balance the sweetness in the juice by providing a contrasting flavor profile.
An acid will turn the red cabbage indicator red, pink, or magenta in color. This change occurs because the anthocyanin pigments in the cabbage react with the acidic solution, causing a color change.
Red cabbage is one of many varieties of cabbage grown in temperate regions worldwide. Its juice contains the pigment cyanidin, which is used as a homemade indicator of acids and alkalies because it turns the purple colored juice pink when an acid is added and blue when mixed with an alkali (or colorless in a strong alkali solution).

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.
no it reacts only with rainbow cabbage juice and not red
Some cheeses have citric acid added to them to improve the melting qualities of the cheese. Quick Mozzarella is a classic example of this. Many Processed cheeses have citric acid in them to give a smooth melting cheese.
