A Buffer Solution is used to:
Correct answer: B. Resist changes in pH
- A. Change the pH drastically
- B. Resist changes in pH
- C. Act as a strong acid
- D. Act as a strong base
- E. Add color to the solution
Explanation
A buffer contains a weak acid and its conjugate base (or vice versa). It neutralizes added acids or bases, maintaining nearly constant pH. Thus, its main role is to resist pH changes

About Analytical Chemistry
Analytical chemistry identifies and measures substances using separation and instrumental methods. Chromatography is studied through stationary and mobile phases, retention and Rf values, while spectroscopy connects absorption of electromagnetic radiation with molecular structure and supports qualitative and quantitative analysis through techniques such as UV-visible and infrared spectroscopy.
