Question

The sum of the primary and secondary valence of the metal M in given complex [M(en)2(ox)]cl is

Answer 1

The sum of the primary and the secondary valency of the metal in the given complex is equal to, 3

Explanation:

• the primary valency indicates the main valency of the metal which includes both the cation and anion. In case of this for ethylene diamine the valency is equal to plus 2 whereas in case of ox it is -2.

• if the chloride Ion also has a valency of -1 then the primary valency of the metal is equal to  + 1 where as the secondary valency includes only the substances within the the complex state of the metal which includes + 2 hence the sum is + 3
