Answer:
Every substance around you, from the orange juice you drink and the water you use to bathe to the saliva in your mouth, has a pH level. Testing the pH of liquid, which can be done in different ways, tells you whether it is acid, alkaline or neutral. On the pH scale, which runs from 0 to 14, 7 is neutral, anything below 7 is acidic, and anything above 7 is alkaline.
