How can the pH of a solution be roughly determined using pH paper?

Options

  1. ApH paper provides an exact pH measurement.
  2. BpH paper changes color based on the concentration of hydrogen ions.
  3. CpH paper is used to measure the density of a solution.
  4. DpH paper has different colors in solutions of different pH, allowing for a rough estimation of the pH.

Correct answer

D. pH paper has different colors in solutions of different pH, allowing for a rough estimation of the pH.

Step-by-step solution

pH paper changes color in solutions of different pH, providing a rough estimation of the pH level.
