Expert Answer:

Primary valence coresponds to the oxidation state of the central metal ion. It issatisfied by negative ions only.
Therefore, in the givem compound, the primary valency of tetraaminedichlorochromium (III)chloride is + 3.
 
Each Cl inside the brackets is -1 
the final Cl is -1 

So Cr is +3
