pH Scale
Definition
The pH scale measures how acidic or basic an aqueous solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.
Analogy
The PH scale is like measuring temperature. Just as we use a thermometer to see if it's hot or cold outside, the pH scale tells us how acidic or basic a solution is.
