(B) In the complex ion $[AlCl(H_{2}O)_{5}]^{2+}$,let the oxidation state of $Al$ be $x$. $x + (-1) + 5(0) = +2$ $x - 1 = +2$ $x = +3$. Thus,the oxidation state of $Al$ is $+3$. The covalency is the total number of coordinate bonds formed by the central metal atom with the ligands. Here,$Al$ is bonded to $1$ $Cl^-$ ion and $5$ $H_2O$ molecules,so the total number of coordinate bonds is $1 + 5 = 6$. Therefore,the oxidation state $(+3)$ and covalency $(6)$ are not the same.

Formula of the complexes	Moles of $AgCl$ precipitated per mole of complex
$(I) \ CoCl_3 \cdot 6 H_2O$	$3$
$(II) \ NiCl_3 \cdot 6 H_2O$	$2$
$(III) \ Co(SO_4)Br \cdot 5 NH_3$	$1$

Are the oxidation state and covalency of $Al$ in $[AlCl(H_{2}O)_{5}]^{2+}$ same?
