Baking Soda is definitely a base and not an acid, so the cabbage juice will turn blue. It turns pink in an acid, like vinegar. You can test it yourself at home with things you probably already have around your house.
What happens when you cook red cabbage with baking soda?
The cabbage juice is called an indicator because it can tell you the pH of a solution based on the color that it changes. The vinegar will turn the cabbage juice red because it is an acid (acetic acid). The baking soda will turn the cabbage juice greenish-yellow because it is a base (sodium bicarbonate).
What happens if you add baking soda to cabbage water?
Adding baking soda to the cabbage juice makes it a neutral base. When you add liquids to the cabbage juice, very acidic solutions will turn it a red color; neutral liquids make a purplish color; and basic solutions will make cabbage juice a greenish-yellow.
What is the colour of red cabbage in baking soda?
This experiment is used to test for different types of molecules called acids and bases. The cabbage juice turns a greenish blue color when it meets a base and reddish color when it meets an acid! This means our baking soda and Windex are bases and our vinegar and lemon juice are acids!
How do you keep red cabbage from losing its color?
Add lemon juice, vinegar, wine or another acidic liquid to the dish while the cabbage is cooking. While the alkaline quality of hard water can discolor the cabbage, the acidic quality of vinegars and other liquids helps protect the color.

What is the aim of the red cabbage experiment?
Use red cabbage to create a pH indicator. It can tell you whether something is an acid or a base, as well as how acidic or basic it is, based on how much the color changes. Use your new pH indicator to see how acidic and basic different items around your house are. Keep reading to learn all the details.
Why did my cabbage turn pink?
The water soluble red pigment leaking out of fresh cut leaves leads to a discoloration of the plant material. To avoid leakage, the red cabbage leaves are slightly dried out, which gives a poorer, less fresh appearance as, for example, white cabbage.
Can you cook purple cabbage just like green cabbage?
Green Cabbage. Red and green cabbage can be used interchangeably in most recipes. The difference between cooking green cabbage and red cabbage is just one extra step.
