What is the term used to describe a solution that resists changes in pH when small amounts of an acid or a base are added?
A. Saturated solution
B. Colloidal solution
C. Buffer solution✓ Correct Answer
D. Supersaturated solution
💡 Solution & Explanation
A buffer solution consists of a weak acid and its conjugate base or a weak base and its conjugate acid that effectively resists drastic pH shifts upon small acid or base additions. Saturated solutions simply contain the maximum dissolved solute at a given temperature without any specific pH stabilization properties. These chemical systems are vital for maintaining stable biological environments.
