Ever wondered why lemons taste so sour or why your stomach doesn't dissolve itself? The answer lies in acidity and pH levels! Essentially, pH is a scale from 0 to 14 that measures how acidic or alkaline (basic) a substance is.
Acids, like lemon juice and vinegar, have a pH below 7. The lower the number, the stronger the acid. On the other hand, bases, such as baking soda and soap, have a pH above 7. A pH of 7 is considered neutral, like pure water.
Understanding pH is crucial in many areas, from cooking and gardening to medicine and environmental science. For example, your body needs to maintain a specific pH balance for optimal function. In gardening, knowing the pH of your soil helps you choose the right plants. So next time you taste something sour, remember the power of pH!
