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.

What happens when sodium hydroxide is added to red cabbage juice?
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.
An indegestion powder contains sodium hydrogencarbonate and a small amount of citric acid. the powder starts to fizz when it is added to water. what gas is given off when the mixture fizzes?
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.

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.
