When aluminium chloride is dissolved in water, it gives

$A$ coordination complex contains $Co^{3+}$,$Cl^{-}$,and $NH_3$. When dissolved in water,one mole of this complex gives a total of $3$ moles of ions. The complex is

$1 \ mol$ of an octahedral metal complex with formula $MCl_{3} \cdot 2 \ L$ on reaction with excess of $AgNO_{3}$ gives $1 \ mol$ of $AgCl$. The denticity of ligand $L$ is ...... . (Integer answer)

Ammonia acts as a ligand but ammonium ion does not form complexes because

For the coordination compound $[Co(H_2O)_4SO_3]Cl$,the coordination number,oxidation state,number of $d$-electrons,and number of unpaired $d$-electrons of the metal ion are respectively:

Which of the following is an example of a hexadentate ligand?
