In the reaction between CuSO4 and Mg, magnesium (Mg) is oxidized while copper (Cu) is reduced. Magnesium loses electrons to form Mg²⁺ ions, indicating oxidation, while copper ions (Cu²⁺) gain electrons to form elemental copper, indicating reduction. Thus, Mg is the reducing agent and Cu²⁺ is the oxidizing agent in this reaction.
In the nonspontaneous redox reaction involving magnesium (Mg) and copper ions (Cu²⁺), magnesium acts as the reducing agent, while copper ions are reduced to copper metal. The standard reduction potential for Cu²⁺/Cu is +0.34 V, and for Mg²⁺/Mg, it is -2.37 V. The overall cell potential (E°) can be calculated as E° = E°(reduction) - E°(oxidation), which yields E° = 0.34 V - (-2.37 V) = 2.71 V. Since the reaction is nonspontaneous, the cell potential would be negative under standard conditions.
The formula for the ionic compound formed by magnesium ions (Mg2+) and nitrate ions (NO3-) is Mg(NO3)2. The formula for the ionic compound formed by calcium ions (Ca2+) and nitrate ions (NO3-) is Ca(NO3)2.

In a redox reaction involving magnesium (Mg) and copper ions (Cu²⁺), magnesium is oxidized and copper is reduced. The standard reduction potential for Cu²⁺ to Cu is +0.34 V, while the standard reduction potential for Mg²⁺ to Mg is -2.37 V. The overall cell voltage (E°) for the reaction is calculated as the difference between these potentials: E° = E°(reduction) - E°(oxidation) = 0.34 V - (-2.37 V) = +2.71 V. Since this voltage is positive, the reaction is spontaneous under standard conditions, contrary to the premise of being non-spontaneous.

The overall voltage for the nonspontaneous redox reaction involving magnesium (Mg) and copper (Cu) can be determined using standard reduction potentials. The reduction potential for Cu²⁺ to Cu is +0.34 V, while the oxidation potential for Mg to Mg²⁺ is -2.37 V. The overall cell potential (E°cell) is calculated by adding the reduction potential of the cathode (Cu) to the oxidation potential of the anode (Mg), resulting in E°cell = 0.34 V - 2.37 V = -2.03 V. Since the value is negative, the reaction is nonspontaneous under standard conditions.
The balanced chemical equation for the reaction between magnesium and copper(II) nitrate is: Mg + Cu(NO3)2 -> Mg(NO3)2 + Cu
Cu & MgSO4 do NOT react. because in the Reactivity Series magnesium is MORE reactive than copper. So Mg will preferentially oxidise before Cu, Since it is already oxidised in MgSO4 as the ion Mg^(2+), it has already reacted, by ionising two electrons.
