What is the oxidation state of oxygen in Fe₂(CO₃)₃?

Question

Quizplus · Accepted Answer

In the molecule Fe₂(CO₃)₃, the oxidation state of Fe is +2. The oxidation state of S is -2. In CO₃, the oxidation state of C is +2 and the oxidation state of S is -2. Thus, to determine the oxidation state of O, we can set up the equation: (oxidation state of Fe) + (2 × oxidation state of S) + (oxidation state of O) + (oxidation state of C) + (3 × oxidation state of O) + (2 × oxidation state of S) = 0 Plugging in the known oxidation states, we have: +2 + (2 × -2) + (oxidation state of O) + (+2) + (3 × oxidation state of O) + (2 × -2) = 0 Simplifying: -2 + (4 × oxidation state of O) = 0 (4 × oxidation state of O) = 2 oxidation state of O = -0.5 Since the oxidation state of O is a decimal, the closest whole number oxidation state is -2. Therefore, the answer is E.
