Questions and Answers
Which of the following statements is true regarding buffers?
How do buffers resist changes in pH?
What determines the ratio of acid to base in a buffer?
Study Notes
- The kidneys and lungs work together to maintain blood pH of 7.4
- Buffers in the blood help control pH by resisting changes
- Buffers consist of weak acid and its conjugate base (salt)
- Weak acid and salt concentrations are large compared to ions added or removed
- When protons are added, some base is converted to weak acid
- When hydroxide ions are removed, weak acid is converted to base
- Acid and base concentration changes are small relative to amounts present in solution
- Buffers work by maintaining a stable ratio of acid to base
- The ratio of acid to base is determined by the pKa of the buffer
- Buffers are important in maintaining the pH of biological systems.
