What is the pH scale used to measure, and what does a pH of 7 represent on the scale?

Options

  1. AThe pH scale measures the concentration of hydroxyl ions [OH⁻], and a pH of 7 represents a basic solution.
  2. BThe pH scale measures the concentration of all ions in a solution, and a pH of 7 represents a neutral solution.
  3. CThe pH scale measures the acidity or alkalinity of a solution based on hydrogen ion concentration, and a pH of 7 represents a neutral solution.
  4. DThe pH scale measures the concentration of water molecules in a solution, and a pH of 7 represents pure water.

Correct answer

C. The pH scale measures the acidity or alkalinity of a solution based on hydrogen ion concentration, and a pH of 7 represents a neutral solution.

Step-by-step solution

The pH scale is used to measure the acidity or alkalinity of a solution based on hydrogen ion concentration, and a pH of 7 represents a neutral solution.
