pH Scale
What is pH? The definition of pH is the potential of hydrogen
What IS a pH scale? A pH scale measures how acidic or basic a substance is by its quantity of hydrogen ions
The pH scale ranges from 0-14. The pH number assigned to a substance indicates whether a substance is an acid or a base, as well as how strong or weak the substance is. Let's take a closer look at the numbers on the pH scale:
o 1.0-3.0= strong acid
o 3.1-6.9= weak acid
o 7 = neutral
o 7.1-10= weak base
o 10.1-14= strong base
In conclusion, the closer the pH number is to 7, the stronger the acid, while the closer the pH number is to 14, the stronger the base.
o 1.0-3.0= strong acid
