What color does an acid turn if red cabage indacator is added?
Acids turn red/pink when red cabbage indicator is added. Alkali/bases turn blue/green. Neutrals turn purple.
Could you determine the relative pH of the liquids by the varying color of the cabbage indicator?
Yes, the color of the cabbage indicator can change based on the pH of the liquid it is exposed to. Typically, acidic solutions turn the indicator red or pink, neutral solutions turn it purple, and basic solutions turn it green or yellow. By observing the color change in the cabbage indicator, you can estimate the relative pH of the liquids being tested.
What colour does alkali turn in cabbage?
Alkalis turn red cabbage juice blue/green/yellow.
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.
How can you use toothpaste to show that red cabbage is an indicator?
If you blend red cabbage with water (the best ratio for this is 1:2, one cabbage leaf for two cups of water) and then add toothpaste the mixture will turn green. This indicates that toothpaste is a base. If you add vinegar instead the solution will turn red, indicating an acid.

What color does baking soda change when mixed with cabbage juice?
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.
What colour does alkali turn in cabbage?
Alkalis turn red cabbage juice blue/green/yellow.
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.
What color does cabbage juice turn in a base?
Cabbage juice changes color in a basic solution, turning from purple to green or blue. This is due to the pH indicator properties of anthocyanins in the cabbage, which shift in color depending on the acidity or basicity of the solution. In more alkaline environments, the pigments reflect different wavelengths of light, resulting in the color change.
What colour does conditioner turn when mixed with red cabbage?
When conditioner is mixed with red cabbage, it typically changes color due to the pH indicator properties of the cabbage. Red cabbage contains anthocyanins, which can shift in color depending on the acidity or alkalinity of the mixture. If the conditioner is acidic, the mixture may turn a reddish or pinkish hue, while a more alkaline conditioner can result in a blue or greenish color. The exact shade will depend on the specific pH of the conditioner used.
What would baby shampoo colour turn to when mixed with cabbage juice?
When baby shampoo is mixed with cabbage juice, which contains anthocyanins that change color based on pH, the resulting color will depend on the pH of the shampoo. If the baby shampoo is slightly acidic, the mixture may turn a pink or red color. If it is more neutral or slightly basic, the color could shift to purple or greenish. This demonstrates the pH indicator properties of cabbage juice.
What color does red cabbage juice change to if a base is added?
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.
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.
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.
When adding hydrochloric acid to red cabbage juice what color will it return?
It will turn greenish . 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.
