How do you extraction a carrot as an acid base indicator?

To extract a carrot as an acid-base indicator, first, grate or chop the carrot into small pieces and then blend it with a small amount of water to create a puree. Strain the mixture through a fine sieve or cheesecloth to obtain the liquid extract, which contains natural pigments like beta-carotene. This liquid can be used to test pH by adding it to acidic or basic solutions, where it may change color, indicating the pH level. The color change typically ranges from reddish in acidic conditions to yellow in neutral or alkaline conditions.
