What color will lemonade turn into when red cabbage indicator is in it and why?
Lemonade will turn pink when red cabbage indicator is added to it. This color change is due to the red cabbage indicator being sensitive to pH levels. The acidity of the lemonade will cause the red cabbage indicator to change color to pink.
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.
Why is the universal indicator more useful than the red cabbage?
The universal indicator is better than the red cabbage indicator because the universal indicator has a wider range of pH that it can explain why a substance is acidic or basic. The red cabbage indicator only tests the substance if it is an acid or a base. Also, the universal indicators are made carefully and it is manufactured in a precise manner so the results are very reliable. Red cabbage indicators will vary in concentration which could cause errors to occur in determining the pH of a substance.

Why does cabbage juice change pink in aspirin?
Cabbage juice contains a pH indicator called anthocyanin, which changes color in response to the acidity or alkalinity of a substance. When cabbage juice is mixed with aspirin, which is acidic, the anthocyanin reacts to the pH change, resulting in a pink color. This color change is a visual representation of the acidic nature of aspirin, demonstrating how natural indicators can be used to gauge pH levels.
Why does cabbage indicator stay the same colour in water?
Cabbage indicator stays the same color in water because water has a neutral pH, which does not cause the indicator to change its color. The pigment in cabbage indicator changes color in response to changes in the pH level of its environment, but since water has a pH level close to 7 (neutral), there is no significant change in color.
What colour changes when red cabbage indicator is added to acid solutions?
When red cabbage indicator is added to acid solutions, it changes to a reddish-pink color. This change occurs due to the presence of anthocyanins in the cabbage, which react with the hydrogen ions in the acid, resulting in a shift in color. In contrast, in basic solutions, the indicator turns green or blue.

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 is the color of marigold flower indicator when acidic substance is added to it?
When an acidic substance is added to marigold flower indicator, the color generally turns red or pink. This color change indicates the presence of acidity in the substance being tested.
