What is the oxidation number of O in H₂O₂?

Question

Quizplus · Accepted Answer

In the given compound, the oxidation number of hydrogen is +1 and the oxidation number of sulfur is -2. Since the overall charge of the compound is 0, the sum of the oxidation numbers of all the elements must also be 0. Thus, we can set up the following equation:

(+1)(x) + (-2)(4) + (x) + (-2)(4) + (x) + (-2)(4) + (+1)(x) + (-2)(4) = 0

Solving for x, which represents the oxidation number of oxygen, we get:

x = -1

Therefore, the oxidation number of O in the given compound is -1, which is option B.
