Red in acidic solution
it will be purple
In the light of my expierience the colour is purple.
Alkalis turn red cabbage juice blue/green/yellow.
There is no such thing as purple cabbage juice because red cabbage juice is actually already purple, its just called red cabbage jucie.
blue-pinky colour.
no it reacts only with rainbow cabbage juice and not red
Yes it is. Because ive tried it on baking soda (A BASE) and it showed blue colour. So basically it shows the colour table according to the red cabbage juice
Which is more accurate- the pH paper or the red cabbage juice and why?
Red cabbage juice will turn pink when an acid is added to it. Due to the acids in a carbonated drink, 7up till turn the juice a pink colour.
To make a cabbage change colour you usually use red cabbage you cut the cabbage up and then you dip it in a bowl of of vinegar /lemonade this changes its colour because cabbage juice works as a acid/ alkaline indicator (eg red for acid) glad to help Jordan
It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.
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.
