3 cards from this section. Quick, good the night before a test.
What is the main function of a buffer solution?
Think about the role of buffers in biological systems like blood.
What components generally make up a buffer?
Consider the acid-base pairs you've learned about.
What is a buffer solution primarily composed of?
Think about what components allow buffers to regulate pH.
True or False: The effectiveness of a buffer decreases when the concentrations of its components are not equal.
What happens if one component is much higher than the other?
Calculate the pH of a buffer solution containing 0.2 M acetic acid and 0.1 M sodium acetate. Given that the pKa of acetic acid is 4.76.
Apply the equation carefully, ensuring you watch the concentrations.
A buffer solution has an initial pH of 4.50. After adding a strong acid, the pH drops to 4.20. What does this indicate about the buffer's capacity?
Consider how much acidic neutralization occurs with small changes in pH.
