Question

The Valency of Cr in the complex [Cr(H2O)+Cl2] ???

Answer 1

Answer:

primary valency +2. Secondary valency of Cr is 4.

Explanation:

In the given molecule, there are 2 Chloride ions and hence the charge (i.e., primary valency) of Cr is (+2). On the other hand, there are four H20 molecules directly surrounds the central Cr(II) ion. Hence Secondary valency of Cr is 4.
