Question

A non-stoichiometric compound is a compound that cannot be represented by a small whole-number ratio of atoms, usually because of point defects in the crystal lattice. What is the average oxidation state of vanadium in ? What is the average state of vanadium in VO 1.19? If each vanadium atom has either a 2 or 3 oxidation state in this compound, what percentage of the vanadium atoms are in the lower oxidation state?

Answer 1

let x be the percentage of the 2 oxidation state
2 oxidation state vanadium bonds with 1 oxygen
3 oxidation state bonds with 1.5 oxygen.
1*x+1.5*(1-x)=1.19
x+1.5-1.5x=1.19
0.31 = .5x
x = .62
hope it helps
