Substances that are considered acidic are also called alkaline.
The pH scale measures how acidic or alkalizing a substance is. The pH scale ranges from 0 to 14. A pH of higher than 7 is alkalizing (also called basic). A pH less than 7 is acidic and a pH of 7 is considered neutral.pH stands for âpotential hydrogenâ. pH is defined as âthe measurement of electrical resistance between negative and positive ions in the bodyâ. pH of higher than 7 is alkalizing (also called basic).
