Are red cabbages acidic?
It is neither basic or acidic. A pH less than 7 means the solution is acidic while a pH greater than 7 means the solution is basic. The lower the pH, the more acidic a solution is. Red cabbage contains a chemical called anthocyanin that changes color depending on the acidity of its environment.
Is cabbage acidic or basic?
Cabbage has a pH level ranging between 5.50-6.75. This makes it one of the least acidic vegetables and safe to consume on a low-acid diet. What’s more, this veggie doesn’t become more acidic in your stomach and can even help in excess acid absorption.
Is purple cabbage an acid?

Is red cabbage a good pH indicator?
Discussion: Red cabbage is useful as a pH indicator because the leaves contain a pigment molecule from the family of anthocyanins (shown below) which are responsible for many of the red/purple/blue colors observed in fruits and vegetables. In neutral solutions, the color observed is purple.

How do you make a pH indicator out of red cabbage?

What happens when red cabbage is added to acid?
Red cabbage, commonly found in homes, can make a pH indicator solution. The pigment molecule flavin or anthocyanin found in cabbage changes colour based on the solution’s acidity. When the purple solution reacts with something acidic, it turns red, and when it reacts with something basic, it turns green.
Is red cabbage indicator accurate?
Based on the results, it seems that the Red Cabbage Indicator is an efficient pH buffer; while not precise, it is, indeed, accurate (the data for a pH of 9 may be an outlier; hence the accuracy and not precision).
Which acid is present in cabbage?
Answer. CABBAGE CONTAINS OXALIC ACID.
What is the pH of lemon juice?
