Question

Consider the following chemical reaction. Mg(s)+Ni(NO3)2(aq)⟶Ni(s)+Mg(NO3)2(aq)

Answer 1

Answer:

The nickel(II) ion is the oxidizing agent .

Explanation:

The reaction given in the question is as follows -

Mg (s)  + Ni(NO₃)₂ (aq) ---- > Ni (s)  +  Mg(NO₃)₂ (aq)

From , the above equation , the change in oxidation state from the reactant t to the product is as follows -

• Mg is 0 to +2 ,

Since ,

The oxidation state is increasing , this is  oxidation process .

and , Mg , is a reducing agent .

• Ni⁺² is +2 to 0

Since ,

the oxidation state is decreasing , this is the reduction process .

and ,  Ni⁺² , is an oxidizing agent .

,

Hence , The correct statement is -

The nickel(II) ion is the oxidizing agent .
