Answer 1

Explanation:

Oxidation and Reduction are two types of reaction related to the addition or removal of hydrogen and oxygen. But we can explain these reactions by using Electronic concept also.

Electronic Concept:

As the name says, in terms of lose and gain of electrons, Oxidation and Reduction can be defined as:

• Oxidation takes place by the loss of electrons, negative charge will decrease.
• Reduction takes place by the gain of electrons, negative charge will increase.

Coming to the Question:

With respect to our above electronic concept, Option A is incorrect because it doesn't matches with the definition. But, along with this Option C which says:

• Na ➝ Na+¹ + e- is reduction

is also wrong because Na atom is releasing one electron to form an cation. So, this is oxidation. And similarly Option D is Reduction.

So, the incorrect statements are:

$\large{ \therefore{ \underline{ \boxed{ \purple{ \bf{Options \: A, C \: and \: D}}}}}}$

And we are done !!
