There are many instances where you stumble upon items in your closet and kitchen, not sure whether they are acidic or basic. With this PH indicator, you will be able to tell the difference and learn more about what separates these two categories.
So, how does it work?
This pH stuff might sound confusing, but its a way that scientists measure the acidic and basic properties of substances. This measurement scale ranges from 0-14. Substances with a low pH (below 7) are considered acids. Anything with a pH of 7, like water, is considered neutral. Substances with a pH greater than 7 are considered basic. Acids tend to be sour and bases tend to be bitter. The cabbage is able to detect these properties because it has a water soluble pigment called anthocyanin, which changes color once it comes in contact with an acid or base. Be sure to test a variety of beverages at home and have fun!
