Imagine a tiny, invisible superhero that lives in fruits like lemons and oranges. That's citric acid! It's what makes sour candies taste so tart and helps keep your favorite juice from going bad. It’s a natural part of many fruits, giving them their bright, zesty flavor. You can’t see it, but you can definitely taste its tangy magic!

Long ago, people knew lemons were sour, but they didn't know exactly why. In 1784, a clever scientist named Carl Wilhelm Scheele figured out how to get this sour stuff, citric acid, out of lemon juice. He did it by boiling lemon juice with chalk! It took a long time for scientists to understand all its secrets and how to make it themselves.
