All ligands are .....

The coordination number of $Fe$ in the complexes $[Fe(CN)_6]^{4-}$,$[Fe(CN)_6]^{3-}$ and $[FeCl_4]^-$ would be respectively:

Sodium thiosulphate is used to remove the unexposed $AgBr$ from photographic films by forming a complex. In this complex of silver,the coordination number of silver is

The sum of the coordination number and the oxidation number of the metal $M$ in the complex $[M(en)_2(C_2O_4)]Cl$ (where $en$ is ethylenediamine) is:

The compounds having coordinated water are

$I$. $CrCl_3 \cdot 6 H_2 O$

$II$. $BaCl_2 \cdot 2 H_2 O$

$III$. $CuSO_4 \cdot 5 H_2 O$

The complex salt $[Cr(H_2O)_4Br_2]Cl$ gives a test for which of the following ions in its aqueous solution?
