Chemistry - Coordination Chemistry Question with Solution | TestHub
Werner was able to explain the nature of bonding in complex , and he concluded that in complex the metal show two different valency
(1) Primary valency
(2) Secondary valency
For one of the isomer of , If we add excess solution in 1 mole isomer of , then formation of silver halide precipitate take place , which is completely insoluble in solution then formula of isomeric complex is.
Options:
Answer:
Solution:
The correct option is (B) .
When excess is added, it reacts with the counter-ions (outside the coordination sphere) to form a silver halide precipitate.
precipitate is soluble in ammonia (), whereas precipitate is completely insoluble in .
Since the question states the precipitate is completely insoluble in , the precipitate must be , meaning iodide () ions are outside the coordination sphere.
Therefore, both ions act as counter-ions, while ions and ligands remain inside the sphere, giving the formula .
