2 cards from this section. Quick, good the night before a test.
What components are typically used to create an acidic buffer?
Think of common buffers you might use.
What is the Henderson-Hasselbalch equation used for?
What relationships does it establish?
What is the function of a buffer solution?
Remember, what do buffers do?
What is the Henderson-Hasselbalch equation used for?
Think of how pH is defined in this context.
Given that the pKa of a weak acid is 4.76, calculate the pH of a buffer solution where the ratio of the concentrations of its salt to the weak acid is 0.5.
Consider how the ratio impacts the logarithm in the equation.
A solution is made by combining 0.1 M acetic acid with 0.1 M sodium acetate. If the solution is diluted by half, how does the pH change?
Think about how dilution affects the concentrations.
