Consider the following reaction :21-12(g) + 02 (g) 2H20 (1)
Which one of the following statements about the reaction given above is correct?
The oxidation state of hydrogen increases while that of oxygen decreases
The oxidation state of hydrogen decreases while that of oxygen increases
There is no change in the oxidation state of hydrogen as well as that of oxygen
During the reaction, hydrogen is reduced while oxygen is oxidized
- Option 1: The statement suggests hydrogen's oxidation state increases and oxygen’s decreases. But in the reaction from H2 to H2O, hydrogen stays at +1, and oxygen changes from 0 to -2. So, this option is incorrect.
- Option 2: Suggests a decrease in hydrogen's oxidation and an increase in oxygen’s. But, actually, hydrogen remains at +1, and oxygen goes from 0 to -2. Thus, this statement is incorrect.
- Option 3: States no change in oxidation states for hydrogen and oxygen. However, oxygen’s state changes from 0 in O2 to -2 in H2O, so this is incorrect.
- Option 4: Indicates hydrogen is reduced and oxygen is oxidized. The truth is hydrogen stays at +1, and oxygen is reduced from 0 to -2.
Based on the reaction, the correct answer is:
- Option 4: During the reaction, hydrogen is reduced while oxygen is oxidized. Rather, hydrogen’s oxidation state stays the same.
