Unit 9: Acid-Base Chemistry

Topics:

• writing net ionic equations for acid-base reactions
• conjugate acid-base pairs
• ionization of water: K_w and the pH concept
• acid-base equilibria and their ionization constants (K_a and K_b)
• acid/base strength: the stronger the acid, the higher its K_a value and the weaker its conjugate base
• neutralization reactions
• finding pHs for SA, WA, SB, WB, polyprotic acids, salt solutions, buffer solutions, and neutralizations
• composition and properties of buffer solutions: how do you make a stable buffer solution at a chosen pH?
• acid-base titrations (SA/SB, SA/WB, and WA/SB)
• indicators: what are they? how do they work? how do you choose one?
• equivalence point vs. titration endpoint: what's the difference?
