[Co(NH3)6]Cl3

Homework Answers

Answer #1

[Fe(CN)6]3– -----------------------> coordination

Cr(gly)3 ----------------------------> chelation

[Ni(en)3]3+ ----------------------------> chelation

[Co(EDTA)]– ----------------------------> chelation

[Rh(NH3)5I]I2 ------------------------> coordination

[Co(NH3)6]Cl3 ---------------------> coordination

explanation :

if the complex contain all monodentate ligands that is called simle coordination complex

if te compoux contain polydentate ligands that is called chelating complex .

gly , en are bidentate ligands

EDTA is hexadentate ligand

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...
