TABLE 12.3 a. Conjugate pairs b. Line near top of table: i. Above 1. Strong Acids (Non-Basic) ii. Below 1. Weak Acids c. Weaker going down Friday, November 10, 2006 BASES IN WATER 1. Dissolving bases in water a. React with water to from OH 1-NH 3 + H 2 O = NH 4 1+ + OH 1-[NH 4 1+ ][HO 1-] K a = [NH 3 ] 3. TABLE 12.3 a. Line near bottom of table i. Below 1. Strong Bases (Non-Acidic) ii. Above 1. Weak Bases b. Weaker going up o Stronger bases across from weaker acids GOALS • Identify conjugates acid and bases • Names = formulas of oxo-acids and there basic forms • Write reactions of acids & bases with water • Navigate Table12.3...
