Question

Find the oxidation state of sodium in Na2O2.

Solution 1

Let the oxidation state of Na be x. The oxidation state of oxygen, in case of peroxides, is –1.

Therefore,

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

2x - 2 = 0

2x = 2

x = +1

Therefore, the oxidation sate of sodium is +1.

Solution 2

Let x be the oxidation state of Na in Na2O2     2x + 2 (-1) = 0  2x – 2 = 0    2x = 2 x = +1.

  Is there an error in this question or solution?
