Question

what is the oxidation state of S2 in S2 O^-2 6​

Answer 1

Answer:

If x is the oxidation state of S, then...

2x + (-2) × 6 = -2

2x = 10

x = +5

Answer 2

ANSWER

Let x be the oxidation state of S in S2O62−.

Since the overall charge on the complex is −2, the sum of oxidation states of all elements in it should be equal to −2.

2x+6(−2)=−2

x=+5
