4 cards from this section. Quick, good the night before a test.
What does the initial pH represent in a titration?
Think about what factors determine the acidity of the solution.
What occurs in the buffer region of a titration curve?
Consider what a buffer does when an acid or base is added.
What is the significance of the buffer region in a titration curve?
Think about what a buffer does in response to added substances.
True or False: The equivalence point of strong acid-weak base titrations occurs at pH lower than 7.
Recall the nature of the products formed in the titration.
You perform a titration of 50 mL of a weak acid with a known concentration of 0.1 M with a strong base. Given that the pKa of the weak acid is 4.76, which indicator would you use and why?
Consider where the equivalence point will lie based on the nature of the acid.
For a certain titration, you find that the equivalence point occurs when 25 mL of a strong acid has been added to 50 mL of a weak base. Calculate the resulting pH at the equivalence point, considering the weak base's pKb.
Use the relationship between pKa and pKb to solve!
