Special instruments called pH meters are used에서acquire and quantify how acidic or basic the liquid is. They are extremely helpful with various fields. pH meters are used by scientists, farmers, and even chefs! There is a lot we can learn about liquids and how they behave from measuring pH. So today we are going to learn all about pH meters,pH meters, how do they work and why they are important in science and our regular lives!

Before we look further into pH meters, we need to know what pH is! It indicates whether a liquid is acidic, basic or neutral. The pH scale ranges from 0 to 14. As such, a pH of 0 would indicate that the liquid is very acidic and potentially harmful. A pH of 14 is very basic, and that can also be dangerous, in some cases. A pH of 7 is neutral, neither acidic nor basic. Most of the liquids we encounter in everyday life lie between those two ends of the scale. Acidic solutions include lemon juice (which has a pH around 2 and is quite sour!) Soap, on the other hand, is basic and has a pH of roughly 9, and so is slippery to the touch.
