1 C. strong and weak acids and bases 1. strong acids and bases – completely ionized in solution (strong electrolyte) see Table 4.2, BLB p 132 for strong 2. Weak acids and bases – partly ionized in solution (weak electrolyte) 3. The following diagrams represent aqueous solutions of three acids (HX, HY, and HZ) with water molecules omitted for clarity. Rank them from strongest to weakest. D. Identifying strong and weak electrolytes 1. Procedure for determining strong, weak, or non-electrolytes a. ionic or molecular? – ionic are strong electrolytes b. acid? – if no, skip to d. c. strong acid? – strong acids are strong electrolytes – weak acids are weak electrolytes d. molecular base such as NH 3 ? – molecular bases are weak electrolytes – other compounds are likely non-electrolytes 2. Consider solutions in which 0.1 mol of each of the following compounds is dissolved in 1 L of water: Ca(NO 3 ) 2 (calcium nitrate), C 6 H 12 O 6 (glucose), NaC 2 H 3 O 2 (sodium acetate), and HC 2 H 3 O 2 (acetic acid).
