How are buffer solutions with specific pH values prepared?

Options

  1. ABy adjusting the temperature
  2. BBy controlling the ratio of salt and acid or salt and base
  3. CBy using strong acids and strong bases
  4. DBy increasing the concentration of H+ ions

Correct answer

B. By controlling the ratio of salt and acid or salt and base

Step-by-step solution

The paragraph mentions that buffer solutions of known pH can be prepared by controlling the ratio of salt and acid or salt and base to achieve the desired pH.
