Na2[Zn(OH)4] coordination number = _______charge = ______K[Co(H2O)2(C2O4)2] coordination number = _______ charge = _______[Ru(H2O)2(NH3)2Cl2]Br coordination number = _______ charge = _______

Respuesta :

Answer:

Explanation:

Na₂[Zn(OH)₄]   :  2 Na⁺¹  + Zn(OH)₄⁻²

coordination no : 4 , central metal ion is Zn , charge on it  =  + 2

(+ 2 -  4 = -2 )

K[Co(H₂O)₂(C₂O₄)₂] :   K⁺  +  Co(H₂O)₂(C₂O₄)₂⁻

coordination no = 2 + 2 = 4  , two for H₂O and 2 for C₂O₄ ⁻²

charge on metal Co is + 3   [  - 4+ 3  = - 1 ]  

[Ru(H₂O)₂(NH₃)₂Cl₂]Br  = Ru(H₂O)₂(NH₃)₂Cl₂ ⁺¹  +  Br ⁻¹

coordination no : 2+ 2 + 2 = 6 ( 2 for H₂O , 2 for NH₃ , 2 for Cl )

central metal ion is Ru : charge on it = + 3 .

( + 3 - 2 = + 1 )

The coordination number shows the number of ligands attached to the central metal.

A complex is a coordination compound which contains a central metal atom or ion. The coordination number refers to the number of ligands in the complex. The coordination number usually influences the geometry of the complex compound.

The coordination number and the charge on the central metal in each of the complexes are shown below;

Na2[Zn(OH)4] - The coordination number of the complex is 4 and the charge on the central metal ion is +2.

K[Co(H2O)2(C2O4)2] - The coordination number of the complex is 6 and the charge on the central metal is +3.

[Ru(H2O)2(NH3)2Cl2]Br - The coordination number of the complex is 6 and the charge on the central metal is +3.
