Green
its kind of orange and i think the ph of NaOH is 8-10................... double check though coz i tested this with red cabbage juice so i am not sure.................. \\\
dilute sodium hydroxide solution
Lemon juice is more acidic. Lemon juice has a pH of 2, which is very acidic. Sodium hydroxide is alkaline, with a pH of 14. However, I'd consider sodium hydroxide considerably more dangerous, as even a small splash can cause painful burning.
pink
no it reacts only with rainbow cabbage juice and not red
When adding tomato juice to cabbage juice, the cabbage juice turns redish
orange
It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.
As tea ranges from mildly to strongly acidic, the cabbage juice should turn red or pinkish.
