Robert Wu Double Replacement and Solubility Lab Period 1 2/20/08 Pre-Lab Questions 1- Silver nitrate, sodium carbonate, and sodium hydroxide solutions are described as skin and eye irritants. Silver nitrate can stain skin and clothing. This means that I should avoid contact with these chemical by wearing splash goggles and chemical-resistant gloves and apron. 2- . 3- Molecular equations show what atom each atom binds to but do not show the charges of each atom involved. Ionic equations show the charges of each atom and the resulting precipitate but do not show the atoms in the original aqueous compounds before the reaction. Net ionic equations show the atoms (and their charges) involved in forming a precipitate but do not show spectator atoms not involved in the reaction

Unformatted text preview: The cations that are the exceptions to the rule for each anion identified are Ag for NaCl and NaI and Ba and Ag for Na 2 SO 4 4-The anion testing solutions that produced the most precipitates are Na 2 CO 3 , NaOH, and NaPO 4 . The cations that are exceptions to the rule for each anion identified in 4a are anions combined with NH 4 + or Group 1A elements. 5-I expect most bromide salts to be soluble with the exceptions of compounds containing Ag + , Pb 2+ , and (Hg 2 ) 2+ . 6-Ionic Compounds Soluble or Insoluble Exceptions Carbonates Insoluble Group 1A, NH 4 + Chlorides, bromides, iodides Soluble Ag + , Pb + , Hg 2 2+ Hydroxides Insoluble Group 1A, NH 4 + Nitrates Soluble None Phosphates Insoluble Group 1A, NH 4 + Sulfates Soluble BaSO 4 , PbSO 4 , Ag 2 SO 4 , SrSO 4 Alkali Metal Salts Soluble None Ammonium Salts Soluble None...
