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.
What else can I help you with?
What color does red cabbage indicator change to in alkali?
either a green, dark green or blue colour for i have done the test myself
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 is the colour of bromomethyl orange indicator?
Bromomethyl orange indicator is yellow in acidic solutions and orange in basic solutions.
One indicator that changes colour in an acid and alkali solution?
Litmus paper is an indicator that changes color in acid and alkali solutions. In an acid solution, litmus paper turns red, while in an alkali solution, it turns blue.
What is the colour of the universal indicator in the acid?

What is a indicator of acid and alkali?
One common indicator of acids and bases is litmus paper. Litmus paper turns red in acidic solutions and blue in basic solutions. Another indicator is phenolphthalein, which is colorless in acidic solutions and pink in basic solutions.
what name is given to a substance that develops a different colour in different solutions?
An Indicator.
When you add an acid to an alkali it changes to a neutral which colour change would this show with an indicator?
It depends on the indicator and there are quite a few. Methyl Red, Methyl orange and Phenolphthalein are 3 such acid-base indicators. If phenolphthalein is used as the indicator and added to the base it would immediately turn red/pink. As acid is titrated in, the red/pink will disappear and go colorless.
Which liquid or liquids caused the universal indicator to change colour?
The universal indicator changes color in response to the acidic or basic nature of a solution. Acidic solutions will turn the indicator to a red color, while basic solutions will turn it to a blue or purple color. Different liquids with varying pH levels can cause the universal indicator to change color accordingly.
Chemical that changes colour in acids and bases?
