1.

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

Answer»

Solution :No. The oxidation state of Al is `+3 `and the COVALENCY is 6.
Because,
`+2 = Al + CL + 5 (H_(2) O)`
`+2 = x - 1 + 5(0)`
` :. X = +3 = ` oxidation number of Al
Al form one covalent bond Cl form one covalent bond and FIVE covalent bond from with `5 H_(2) O`,
So total 6 covalent bond is present.
