Question

in the synthesis of tris(ethylenediamine)nickel (II) chloride dihydrate lab, give me a good introduction in a clear statement of the problem or project and the reasons for studying it. Please I am stuck.

Answer 1

i will give you some key points you can write nice introduction

the equation for this reaction is

[Ni(H2O)₆]Cl₂ + 3en -------> [Ni(en)₃]Cl₂ ·2H₂O + 4H₂O

1)

Coordinaion compounds are very important some of them are even used as a anticancer agent example is Cis platina so we should know how to prepare the coordination compounds.

2)

You might be studied about chelated ligands will form strong complex than non chelated ligands in theory of coordination chemistry. you need to prove these kind of things

like if you observe here H2O is non chelated ligand where as ethylene diamine is chelated ligand we need to find out the rate of the reaction and stability of the complex then only we can say complexes with chelated ligands are more stable thant non chelated.

3)

if you observe this reaction this is one of the nucleophilic displacement reaction`we can study rate of the inorganic reaction mechanism.

4)

we can study the proerty of the metals means absorbence of coordination complex colour of the coordination complex.
