Question

Covalency of ALCL(H20)5)5+

Answer 1

=>

The common oxidation state of any element is its group number or (group number)-8.

So the common oxidation state of chlorine(group number=7) is 7-8 =-1.

Oxidation state of o is -2.

Oxidation state of H is +1.

In H2o, oxidation state of H and o are balanced.given that total oxidation state is +2.

Sum of all oxidation states is +2, let oxidation state of Al be x.

x+(-1)+5(0)=+2.x=2+1. x=+3. of Al be x. x+(-1)+5(0)=+2.x=2+1. x=+3.
