Step-by-Step Solution:
Step 1 of 3

Chapter 4: Reactions in Aqueous Solutions I. Solubility is the maximum amount of solute that will dissolves in a given quantity of solvent at a specific temperature. II. Solubility Rules:  Alkali (Group AI) = soluble (gives up electrons for positive charge) + 2+ 2+ 2+  Halides (Cl­, Br­, I­) = soluble, except with Ag , Cu , Pb , Hg 2 (takes up electrons for negative charge)  Ammonium compounds (NH ), nitrates(4O ), bicarbonates 3HCO ), and chlorates 3­ (ClO ) = soluble 3  (SO )4= soluble, except with Ag , Ca , Sr , Ba , Hg 2+ 2+ 22+  Hydroxides
