Buffer Pairs

Question

Buffer pairs
A) absorb hydrogen ions
B) absorb hydroxide ions
C) prevent sharp changes in the pH of a solution
D) all of the above

Accepted Answer

Buffer pairs are chemical substances that can absorb both hydrogen ions (H+) and hydroxide ions (OH-) to prevent sharp changes in the pH of a solution. This is achieved by maintaining a relatively constant pH when small amounts of acidic or basic substances are added to the solution. Therefore, buffer pairs can absorb both types of ions and prevent changes in pH, making choice D the best answer.
