Question

Determine the oxidation state of each species. Identify the oxidation state of Ba2+. Identify the oxidation state of Sin SO, Identify the oxidation state of Sin So. Identify the oxidation state of Zn in ZnSO,

Answer 1

1) Ba2+

Oxidation state of mono ion = charge on ion = +2

Answer: +2

2)

SO2

Oxidation number of O = -2

lets the oxidation number of S be x

use:

2* oxidation number (O) + 1* oxidation number (S) = net charge

2*(-2)+1* x = 0

-4 + 1 * x = 0

x = 4

So oxidation number of S = +4

Answer: +4

3) SO42-

Oxidation number of O = -2

lets the oxidation number of S be x

use:

4* oxidation number (O) + 1* oxidation number (S) = net charge

4*(-2)+1* x = -2

-8 + 1 * x = -2

x = 6

So oxidation number of S = +6

Answer: +6

4)

This is compound of Zn2+ and SO42-

Oxidation state of mono ion = charge on ion = +2

Answer: +2
