Have you ever tasted a lemon and puckered up? Lemons have that puckery taste because they're acidic, just like vinegar and some other foods. In this lesson, you'll learn about the pH scale, which scientists use to describe whether something is acidic or basic. Basic is the opposite of acidic. Another word for 'basic' is 'alkaline:' they mean the same thing.
The pH scale goes from 0 to 14: 0 is the most acidic and 14 is the most basic, or alkaline.
So if something has a low pH (close to 0), then it's very acidic, and if it has a high pH (close to 14), it's very basic or alkaline. Plain water is right in the middle of the scale with a pH of 7. This is called a neutral pH, because it's not very acidic or very basic (alkaline).
To get a better idea of pH, it can help to look at some examples from real life. We'll start with the middle of the pH scale: with a pH of 7, plain water is exactly in the center. So if you want to feel and taste something with a neutral pH, go pour yourself a glass of water and take a big drink.
