What Does pH Measure?
Understanding the pH Scale
The pH scale is a measure of the acidity or basicity of a solution. It is a logarithmic scale that ranges from 0 to 14, with 7 being neutral. The pH scale is used to describe the concentration of hydrogen ions (H+) in a solution, which in turn affects the pH.
What is pH?
pH is a measure of the concentration of hydrogen ions (H+) in a solution. It is a fundamental concept in chemistry and is used to describe the acidity or basicity of a solution. The pH scale is a logarithmic scale that ranges from 0 to 14, with 7 being neutral.
How is pH Measured?
pH is measured using a pH meter, which is a device that measures the concentration of hydrogen ions in a solution. The pH meter is calibrated to a specific range, typically 0 to 14, and is used to determine the pH of a solution.

What are the pH Ranges?
The pH scale is used to describe the concentration of hydrogen ions (H+) in a solution. The pH scale is a logarithmic scale that ranges from 0 to 14, with 7 being neutral. The pH ranges are as follows:
- pH 0-1: Strongly acidic
- pH 1-3: Acidic
- pH 4-5: Weakly acidic
- pH 6-7: Neutral
- pH 8-9: Weakly basic
- pH 10-12: Basic
- pH 13-14: Strongly basic
What are the pH Ranges for Different Solutions?
The pH ranges for different solutions are as follows:
- Water: pH 7 (neutral)
- Acidic solutions: pH 0-1
- Basic solutions: pH 7-14
- Neutral solutions: pH 6-7
