Test Tube #
1.5 mL 0.05 M trans-[Co(en)2Cl2]Cl 2
4 3.0 mL 0.05 M trans-[Co(en)2Cl2]Cl
3.0 mL 0.05 M trans-[Co(en)2Cl2]Cl
1.5 mL 0.01 M trans-[Co(en)2Cl2]Cl 5
6 3.0 mL 0.01 M trans-[Co(en)2Cl2]Cl
3.0 mL 0.01 M trans-[Co(en)2Cl2]Cl Brief Procedure
boil—turns red; + 1.5 mL 0.05 M trans[Co(en)2Cl2]Cl 3 mL grayish t1/2
comparison standard for 0.05 M runs
0.05 M run #1
0.05 M run #2
boil—turns red; + 1.5 mL 0.01 M trans3 mL grayish t1/2
comparison standard for 0.01 M runs
0.01 M run #1
0.01 M run #2 6. You now should have six test tubes, each containing 3 mL of solution (see Table I).
There are two sets of three tubes; the concentration in one set of solutions is about
five times that of the other set. Two members of each set contain a green solution of
essentially pure trans-[Co(en)2Cl2]Cl. The third tube of each set contains a grayishpink solution, half of which has been...
