Soluble; SnCl_{2} \rightarrow Sn^{2+} + 2Cl^{-} ### j. Soluble; ZnSO_{4} \rightarrow Zn^{2+} + SO_{4}^{2-} Explanation 1. Determine Solubility Use solubility rules to determine if each compound is soluble or insoluble in water. a. Al(C_{2}H_{3}O_{2})_{3}: **Soluble** (Acetates are generally soluble.) b. Al(OH)_{3}: **Insoluble** (Most hydroxides are insoluble except those of alkali metals and Ba^{2+}.) c. Ba(OH)_{2}: **Soluble** (Barium hydroxide is an exception and is soluble.) d. Ca(ClO_{3})_{2}: **Soluble** (Chlorates are generally soluble.) e. CaSO_{4}: **Insoluble** (Calcium sulfate has limited solubility.) f. Hg_{2}Cl_{2}: **Insoluble** (Mercury(I) chloride is insoluble.) g. K_{2}CrO_{4}: **Soluble** (Potassium compounds are generally soluble.) h. Mg_{3}(PO_{4})_{2}: **Insoluble** (Most phosphates are insoluble except those of alkali metals.) i. SnCl_{2}: **Soluble** (Most chlorides are soluble, except for a few exceptions like Ag^+, Pb^{2+}, Hg_2^{2+}.) j. ZnSO_{4}: **Soluble** (Most sulfates are soluble, except for a few exceptions like Ba^{2+}, Pb^{2+}, Ca^{2+}.) 2. Write Dissociation Equations Write the dissociation equations for the soluble compounds. a. Al(C_{2}H_{3}O_{2})_{3} \rightarrow Al^{3+} + 3C_{2}H_{3}O_{2}^{-} c. Ba(OH)_{2} \rightarrow Ba^{2+} + 2OH^{-} d. Ca(ClO_{3})_{2} \rightarrow Ca^{2+} + 2ClO_{3}^{-} g. K_{2}CrO_{4} \rightarrow 2K^{+} + CrO_{4}^{2-} i. SnCl_{2} \rightarrow Sn^{2+} + 2Cl^{-} j. ZnSO_{4} \rightarrow Zn^{2+} + SO_{4}^{2-}
