Ph scale

Ph scale is use to scale the strength of acid and base. Look at the Ph scale at the bottom. There are  0 to 14, and for 7 it is neutral. It mean that it is either acid or base(ex: pure water).For acid, the strongest acid have a ph close to zero. For base, the strongest base have a ph close to fourteen.

After I learn about this lesson, I know a lot about acid and base. Before I don’t even know what is acid and base so it is kinda hard to catch up with the lesson. However, asking my friend and read more help me a lot. I hope you enjoy this writing and I hope you learn something.
