Cobalt (III) chloride forms several octahedral complexes with amonia.

1.	Cobalt (III) chloride forms several octahedral complexes with amonia. Which of the following will not give test for chloride ions with silver nitrate at `25^@C`?A. `CoCI_(3)` . `6NH_(3)`B. `CoCI_(3)` . `3NH_(3)`C. `CoCI_(3)` . `4NH_(3)`D. `CoCI_(3)` . `5NH_(3)`
Answer» Correct Answer - B No ppt. of AgC1 will be obtained if all the chlorine particles are part of the coordination sphere as in the complex `CoC1_(3)` . `3NH_(3)` or `[Co(NH_(3))_(3)C1_(3)]` . `CoC1_(3)` . `6NH_(3)` `implies [Co(NH_(3))_(6)]C1_(3) implies 3` mol AgC1 `CoC1_(3)` . `implies [Co(NH_(3))_(4)C1_(2)]C1 implies 1` mol AgC1 `CoC1_(3)` . `5NH_(3) implies [Co(NH_(3))_(5)C1]C1_(2) implies 2` mol AgC1
