What is a pH scale?
Quick Answer
The pH scale measures how acidic or alkaline a solution is, usually from 0 to 14. A pH of 7 is neutral, lower numbers are acidic, and higher numbers are basic.
The Full Story
pH is related to the concentration of hydrogen ions in a solution. Because it uses a logarithmic scale, each whole number change represents a tenfold change in acidity. Pure water is close to pH 7 at room temperature, though exact values can vary slightly. The pH scale is vital in chemistry, medicine, agriculture, and environmental science.
Key Facts
1.pH 7 is neutral
2.The scale is logarithmic
3.Lower pH means more acidic solution
