What is pH and How is it Measured?
pH is a measure of the concentration of hydrogen ions in a solution, which indicates its acidity or basicity. The pH scale ranges from 0 to 14, with a pH of 7 being neutral, below 7 being acidic, and above 7 being basic. The pH of a solution is measured using a pH meter or pH paper, which provides a numerical value that represents the solution’s acidity or basicity.
The pH Scale: Understanding the Basics
The pH scale is a logarithmic scale, meaning that each step up or down represents a tenfold change in the concentration of hydrogen ions. For example, a solution with a pH of 6 is ten times more acidic than a solution with a pH of 7, and a solution with a pH of 5 is 100 times more acidic than a solution with a pH of 7.
pH Measurement Methods
There are several methods for measuring pH, including:
- pH meters: These are electronic devices that use a probe to measure the pH of a solution.
