What will be the color of red cabbage extract in lemon juice?

Here's why:

* Red cabbage contains anthocyanins. These are pigments that change color depending on the pH of their environment.

* Lemon juice is acidic. This means it has a low pH.

* Anthocyanins turn pink in acidic solutions.

So, when you mix red cabbage extract with lemon juice, the acidic environment causes the anthocyanins to change color from purple to pink.
