SOLUBILITY RULES Soluble: • All Nitrates, Acetates, Ammonium, and Group 1 (IA) salts • All Chlorides, Bromides, and Iodides, except Silver, Lead, and Mercury(I) • All Fluorides except Group 2 (IIA), Lead(II), and Iron(III) • All Sulfates except Calcium, Strontium, Barium, Mercury, Lead(II), and Silver Insoluble (0.10 M or greater): • All Carbonates and Phosphates except Group 1 (IA) and Ammonium • All Hydroxides except Group 1 (IA), Strontium, Barium, and Ammonium • All Sulfides except Group 1 (IA), 2 (IIA), and Ammonium • All Oxides except Group 1 (IA)
Guidelines for Predicting the Products of Selected Types of Chemical Reaction Key: M = Metal NM = Nonmetal 1. SYNTHESIS: a. Formation of binary compound: A + B → AB b. Metal oxide-water reactions: MO + H2O → base c. Nonmetal oxide-water reactions: (NM)O + H2O → acid DECOMPOSITION: a. Binary compounds: AB → A + B b. Metallic carbonates: MCO3 → MO + CO2 c. Metallic hydrogen carbonates: MHCO3 → MO+ H2O(l) + CO2(g) d. Metallic hydroxides: MOH → MO + H2O e. Metallic chlorates: MClO3 → MCl + O2 f. Oxyacids decompose to nonmetal oxides and water: acid → (NM)O + H2O SINGLE REPLACEMENT: a. Metal-metal replacement: A + BC → AC + B b. Active metal replaces H from water: M + H2O → MOH + H2 c. Active metal replaces H from acid: M + HX → MX + H2 d. Halide-Halide replacement: D + BC → BD + C DOUBLE REPLACEMENT: AB + CD → AD + CB a. Formation of a precipitate from solution b. Acid-Base neutralization reaction COMBUSTION REACTION Hydrocarbon + oxygen → carbon dioxide + water
