Start: Group III Anions Test

8-15: Place 3 drops test soln (SO4²⁻, CO3²⁻, BO3³⁻, CaO4²⁻, C2H3O2⁻, CH3O⁻) + 3 drops AgNO3 TS Observe color & precipitate

8-15a: Test solubility of ppt in HNO3 Record observations

8-16: Place 3 drops test soln + 3 drops BaCl2 Observe precipitate

8-16a: Test solubility of ppt in HNO3 Record results

8-17a: To 3 drops SO4²⁻ TS + 5 drops 6N H2SO4 Warm mixture - note odor of gas Test gas with wet blue litmus paper

8-17b: Dilute 2 drops KMnO4 soln with 10 drops H2O + 3 drops 6N H2SO4 + 3 drops SO4²⁻ TS Observe color change = product formed

8-18: Repeat 8-17a with CO3²⁻ TS instead of SO4²⁻ Gas exposed to limewater using glass rod Note color, name, formula of ppt

8-19: Place 1 mL BO3³⁻ TS in evaporating dish Evaporate slowly to dryness + 2 drops conc. H2SO4 + 10 drops methyl alcohol Ignite - Note color of flame (green) Write name & formula of product

8-20: To 3 drops CaO4²⁻ TS + 3 drops CaCl2 Observe ppt - Test solubility with acetic acid

8-21: To 5 drops C2H3O2⁻ TS + 3 drops AgNO3 + 6 drops 6N NH4OH Heat in water bath (1-5 min) Observe ppt on sides of tube Record color, name, formula

8-22: Repeat 8-21 using CH3O⁻ TS If no ppt, boil mixture 1-2 min Observe ppt on tube sides Record name, color, formula

End: Record results & write Conclusion
