Question

classify giving reasons the following unbalanced half equations as oxidation and reduction. use oxidation number concept​

Answer 1

Answer: Hi , mate for the better understanding let us get it explained first as you said there are unbalanced half equations as oxidation and reduction. use oxidation number concept​

For that 4 possible options erupt

Explanation: oxidation - a

                      reduction - b                                                                                                        

                      neither   oxidation or

                      reduction - c

                      none of these - d

Correct option is

A

Oxidation

The unbalanced half reaction H  

2

​

O  

2

​

(aq)⟶O  

2

​

(g) is oxidation.

The oxidation number of oxygen in H  

2

​

O  

2

​

 and O  

2

​

 is -1 and zero respectively.

Thus, there is an increase in the oxidation number which indicates oxidation.

Hence, the correct option is A.
