The total number of ions present in $K_4[Fe(CN)_6]$ is .....

How many total number of ions are obtained by ionisation of Iron $(III)$ hexacyanoferrate $(II)$ complex?

How many ions are produced from the complex $[Co(NH_3)_6]Cl_2$ in solution?
$i. 6 \quad ii. 4 \quad iii. 3 \quad iv. 2$

According to Werner's theory,the primary valency of a central metal ion is:

The sum of the oxidation state (magnitude) and the coordination number of cobalt in $Na[Co(bpy)Cl_4]$ is $.......$ (Given $bpy = 2,2'-bipyridine$)

The oxidation state and covalency of $Al$ in $[AlCl(H_2O)_5]^{2+}$ are respectively
