Alkalis turn red cabbage juice blue/green/yellow.
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.
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.
What color does red cabbage go when you add alkali?
Red cabbage turns blue or purple in color when you add an alkali, such as baking soda or ammonia. This color change is due to compounds called anthocyanins in the cabbage that react with the alkaline solution.
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.

How does the color change when a strong acid is added an alkali to neutralise?
The color does not change unless an indicator such as litmus or phenolphthalein is being used. If litmus the color change is blue to red If phenolphthalein the change is red to colorless

Why does the color of red purple cabbage extract change its color when cooled?
I've never heard of it changing color when it is cooled, but it does change color with pH, and can be used as an indicator for acids and bases.See the Web Links for more information about using cabbage color as a pH indicator.
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 substance is like litmus that will change color in acids acids alkali?
This substance is called a pH indicator.
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 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.
