Fill the flask carefully tothe calibration mark with 1.0 mol L HNO:(aq), stopper it, and mix well by inversion (25 times). Pour about175 mL of the solution that you just prepared into a clean, dry 250-mL beaker. The concentration of10feFe(NO:):(aq) in this solution is approximately 0.002 mol L'1.Pipette the required volumes of 0.002 mol L1 Fe(NO:):(aq) into flasks 7 to 11. Using the burette, transfer therequired volume of KSCN(aq) (record the burette readings) into flask 8 only.

True or False: (answer directly) 1. If a solution does not form any precipitate when BaCl2 and AgNO3 are separately added, then it is merely distilled water. 2. [Ni(en)3]2+ has higher crystal field splitting energy than [Ni(H2O)6]2+. 3. When solid Ca(OH)2 was dissolved in 0.10 M CaCl2, the solubility product constant was lowered. 4. [Co(NO2)6]3- is an orange octahedral complex with an IUPAC name of hexanitrocobalt(III). 5. In the solubility equilibrium experiment, a saturated solution of Ca(OH)2 maintained in ice bath holds more dissolved calcium than at room temperature. 6. In the hydrogen peroxide system, the detergent is used to detect the formation of H2O molecules. 7. In the selective precipitation experiment, the silver precipitate with lower Ksp dissolves more easily upon the addition of NH3. 8.
