Physical Chemistry: Why does the pH scale run from 1-14?
I was curious about physical chemistry. Can you tell me why the pH scale runs from 1-14?
Sure! The pH scale measures the acidity or alkalinity of a solution. The reason it runs from 1 to 14 is because that range covers the entire spectrum of possible pH values. A pH of 1 is highly acidic, while a pH of 14 is highly alkaline. A pH of 7 is neutral, which means it is neither acidic nor alkaline.
