What is the difference between the 'Equivalence Point' and the 'Endpoint' in a titration?
Equivalence Point: Moles of acid equals moles of base (theoretical). Endpoint: Indicator changes color (experimental).
What are the key differences between a strong acid/strong base titration curve and a weak acid/strong base titration curve?
Strong Acid/Strong Base: No buffer region, sharp equivalence point. Weak Acid/Strong Base: Buffer region present, equivalence point at pH > 7.
Compare and contrast an acid and its conjugate base.
Acid: Proton donor. Conjugate Base: What remains after the acid donates a proton. Differ by one proton.
Label the main components of a titration setup.
1: Burette (Titrant), 2: Erlenmeyer Flask (Analyte), 3: Indicator
What are the steps of an acid-base titration?
- Fill burette with titrant. 2. Measure analyte into flask. 3. Add indicator. 4. Slowly add titrant, swirling, until indicator changes color.
How do you determine the concentration of an unknown solution using titration?
React a known volume of the unknown solution (analyte) with a solution of known concentration (titrant) until the reaction reaches the equivalence point, then use stoichiometry to calculate the unknown concentration.
What is the process for identifying conjugate acid-base pairs?
- Identify the pairs in the reaction. 2. The compound with the extra hydrogen is the acid; the other is the base.
What is the process of using the equation ?
- Identify knowns. 2. Use the equation . 3. Plug in and solve, remembering to convert volumes to liters and account for mole ratios.
