Consider the following chemical reaction. Mg(s)+Ni(NO3)2(aq)⟶Ni(s)+Mg(NO3)2(aq)
Which statement is true for the reaction?
The nickel(II) ion is oxidized.
The nitrate ion is the reducing agent.
The nickel(II) ion is the oxidizing agent.
Metallic magnesium is reduced.
Homework Answers
Solution:-
Balanced reaction equation
Mg(s) + Ni(NO3)2(aq) ---- > Ni(s) + Mg(NO3)2(aq)
In the given reaction equation
Mg is oxidized from 0 to +2 oxidation state and therefore it is acting as reducing agent.
Ni^2+ ion is reduced from +2 to 0 oxidation state therefore it is acting as oxidizing agent.
Therefore the correct statement is
The nickel (ll) ion is oxidizing agent.
