Assessment Objectives
Detailed Breakdown: Acids / Bases
- Define Brønsted-Lowry acids/bases and Lewis acids/bases.
- State the differences between strong/weak acids and concentrated/dilute solutions.
- Identify conjugate acid-base pairs in proton transfer reactions.
- Calculate the $pH$ of strong acids, strong bases, and weak acids/bases ($pKa$ or $pKb$ required).
- Sketch and interpret titration curves for various combinations (SA-SB, WA-SB, SA-WB, WA-WB).
- Calculate the $pH$ of a buffer solution using the Henderson-Hasselbalch equation.
- Predict the $pH$ of salt solutions based on the parent acid and base strength (Salt hydrolysis).
- Choose a suitable indicator for a given titration based on the $pH$ range of the equivalence point.
- Analyze the buffering capacity of chemical and biological systems.
