Data/Results Section Solute Solvent A 1 10.055g KAl(SO 4 ) 2 50mL distilled water @ 30°C B (few grains of solute; few drops of solvent) Fe(acac) 3 Distilled water Methanol Acetone Acetonitrile Methylene chloride Toluene Hexane C (few crystals of solute; 10mL of solvent in each vial) 1 CoCl 2 Sodium silicate 2 Fe(acac) 3 3 CuCl 2 4 FeCl 3 5 CrCl 3 Superscripts in part C of table above reflect the placement of the observation of each crystal in the table below. Observations of Crystals Formed from Each Section Section Number Observation A Only one crystal formed Very geometrical, 0.8x2x1.6 (dimensions), clear, crystalline B Only one crystal formed (two solvents from above table were chosen: one in which Fe(acac) 3 is soluble and one which it is not: hexane and acetone) Very small and rocklike structure, 0.4x0.4x0.4 (dimensions), looks like a tiny black rock
