Solution.

1.

Na4[VCl6]

Z(V) = 2+

Cl - is a weak field ligand, so such a complex will be high-spin.



According to the graph, the magnetic moment of this complex is equal to 1.5.

2.

[Ni(en)3](NO3)4

Z(Ni) = 4+

Ethylenediamine(en) is a strong field ligand, hence this complex is low-spin.



According to the graph, the magnetic moment of this complex is equal to 0.

Answer:

The first complex is a compound of a magnetic transition metal, since the structure of this complex has unpaired electrons that cause the magnetic moment of the complex.

The second complex is a compound of a non-magnetic transition metal, since there are no unpaired electrons in the structure of this complex that would cause the magnetic moment of the complex.

Calcium hydroxide and calcium sulfate are both used to prepare a saturated solution, S. Both solids are only sparingly soluble, and the pH of S is found to be 11.6. (i) Given that the Ksp for calcium hydroxide is 4.0 x 10-5 and the Ksp for calcium sulfate is 2.5 x 10-5 , determine the concentration of sulfate ions present in S.
