Unformatted text preview: 1. H + transfer to H 2 O gives H + 2. H + transfer to base from H 2 O gives OH-vi. NH 3 is a base 1. NH 3 + H 2 O → NH 4 + + OH-a. Water acts as acid vii.HCl + H 2 O → Cl-+ H 3 O + 1. Water acts as base viii. NH 4 Cl 1. NH 4 Cl = acid; also ionic a. NH 4 + has the acidic properties i. NH 4 + + H 2 O → NH 3 + H 3 O + ix. NaOH = strong base 1. NaOH → Na + + OH-III. Conjugate Acid-Base Pairs a. Base NH 3 and Acid NH 4 + i. Differ just by 1 H + b. Conjugate acid of H 2 O = H 3 O + c. Conjugate base of H 2 O = OH-d. Bronsted-Lowry Equation has 2 conjugate acid-base pairs e. NH 4 Cl + NaOH → NH 3 + NaCl + H 2 O i. NH 4 + + OH-→ NH 3 + H 2 O Extra Credit: NaPO 4 + NH 4 Cl → NaCl + NH 3 + H 3 PO 4 Bronsted Lowry for PO 4 3-acting as a base in rxn w/ water Bronsted Lowry for NaPO 4 + NH 4 Cl → NaCl + NH 3 + H 3 PO 4 Due Monday 1/11/10...
