Answer

In the VO^{2+} ion, we have one vanadium atom (V) and an overall charge of +2. Let the oxidation state of vanadium be denoted as x. The oxidation state of oxygen (O) is -2. Thus, we can set up the equation:

$x + (-2) = +2$

Solving for x:

$x = +2 + 2 = +4$

So, the oxidation state of vanadium in VO^{2+} is +4.

Step 2

Determine the oxidation state of VO_{2}^{+}

Answer

For the VO_{2}^{+} ion, we have one vanadium atom and an overall charge of +1. Again, let the oxidation state of vanadium be denoted as x. The oxidation state of each oxygen is -2, and since there are two oxygen atoms, the equation will be:

$x + 2(-2) = +1$

Simplifying this gives us:

$x - 4 = +1$

Solving for x:

$x = +1 + 4 = +5$

Thus, the oxidation state of vanadium in VO_{2}^{+} is +5.
