How do pH values measure acidity and alkalinity?
ChemistryAcids and Bases
Quick Answer
The pH scale measures how acidic or basic a solution is based on hydrogen ion concentration. A pH of 7 is neutral, below 7 is acidic, and above 7 is alkaline.
The Full Story
pH is a logarithmic scale, so each whole number change represents a tenfold change in hydrogen ion concentration. Pure water is close to pH 7 at room temperature, while lemon juice is acidic and soap is basic. The scale helps chemists, biologists, and doctors understand how reactions behave in different environments. Soil, blood, and oceans all depend on pH staying within narrow ranges.
Key Facts
1.pH 7 is neutral
2.Each unit is a tenfold change
3.The scale usually runs from 0 to 14
