Are CO, H2O, CO2, and H2 oxidized or reduced?
Understand the Problem
The question is asking whether the substances (water, carbon dioxide, and hydrogen) are oxidized or reduced in a chemical reaction. It likely relates to redox (reduction-oxidation) reactions where one species is oxidized (loses electrons) and another is reduced (gains electrons).
Answer
CO is oxidized, H2O is reduced, CO2 is the product of carbon oxidation, and H2 is the product of hydrogen reduction.
The final answer is: CO is oxidized, H2O is reduced, CO2 is the product of carbon oxidation, and H2 is the product of hydrogen reduction.
Answer for screen readers
The final answer is: CO is oxidized, H2O is reduced, CO2 is the product of carbon oxidation, and H2 is the product of hydrogen reduction.
More Information
In the reaction CO + H2O = CO2 + H2, the carbon in CO is oxidized from an oxidation state of +2 to +4, while the hydrogen in H2O is reduced from +1 to 0. This means CO loses electrons (oxidation) and H2O gains electrons (reduction).
Tips
Avoid confusing the roles of reducing and oxidizing agents; remember that the reducing agent gets oxidized and the oxidizing agent gets reduced.
