What is the standard reduction potential E for the half-reaction Al3 plus (aq) plus 3e Al(s)?
The standard reduction potential (E°) for the half-reaction ( \text{Al}^{3+} (aq) + 3e^- \rightarrow \text{Al}(s) ) is approximately -1.66 V. This negative value indicates that the reduction of aluminum ions to aluminum metal is not favorable under standard conditions. Therefore, aluminum is more likely to oxidize than to be reduced.

The standard reduction potential (E°) for the half-reaction ( \text{Mg}^{2+} + 2e^- \rightarrow \text{Mg} ) is approximately -2.37 V. This indicates that magnesium ions are reduced to magnesium metal, but the reaction is not favorable under standard conditions due to its negative potential. The value reflects magnesium's strong tendency to lose electrons and form cations, characteristic of its placement in the reactivity series of metals.
What is the standard reduction potential E for the half reaction Mg plus (aq) plus E?
The standard reduction potential (E°) for the half-reaction involving magnesium ions (Mg²⁺) is typically around -2.37 V. This value indicates that magnesium is a strong reducing agent and tends to lose electrons rather than gain them, which is characteristic of metals that readily oxidize. In practical applications, this low potential means magnesium will not easily reduce other species in electrochemical reactions.

How can one determine if a redox reaction will be non-spontaneous?

What is the overall voltage for a redox reaction with the half reactions Mg s -- Mg2 plus plus 2e- and Cu2 plus -- Cu s?
The standard reduction potentials for Mg/Mg^2+ and Cu^2+/Cu are -2.37 V and +0.34 V, respectively. To determine the overall cell potential, you subtract the reduction potential of the anode (Mg/Mg^2+) from the reduction potential of the cathode (Cu^2+/Cu) since the anode is where oxidation occurs. Therefore, the overall cell potential would be 0.34 V - (-2.37 V) = 2.71 V.
Which is the most likely to be reduced A. Fe2 plus B. Ni2 plus C. Cu2 plus D. Zn2 plus?
The most likely to be reduced among the options given is Cu²⁺ (C). This is due to its higher standard reduction potential compared to the other cations, which makes it more favorable to gain electrons and be reduced. Fe²⁺ (A) and Ni²⁺ (B) have lower reduction potentials, while Zn²⁺ (D) is less likely to be reduced because it is more readily oxidized.
If silver and copper are used to make a cell what half-reactions will occur for ag plus aq plus e- ag s e0 equals 0.80 v and for cu2 plus aq plus 2e- cu aq e0 equals 0.34 V?
In the cell, the half-reaction for silver will be Ag+ (aq) + e- -> Ag (s) with a standard reduction potential of +0.80 V. The half-reaction for copper will be Cu2+ (aq) + 2e- -> Cu (s) with a standard reduction potential of +0.34 V. The silver half-reaction will occur at the cathode, while the copper half-reaction will occur at the anode in the cell.
What is overall voltage for a redox reaction with the half reactions Mg(s) Mg2 plus 2e Cu(s)?
To determine the overall voltage for the redox reaction involving the half-reactions ( \text{Mg}(s) \rightarrow \text{Mg}^{2+} + 2e^- ) and ( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu}(s) ), you first need the standard reduction potentials. The standard reduction potential for ( \text{Cu}^{2+}/\text{Cu} ) is +0.34 V and for ( \text{Mg}^{2+}/\text{Mg} ) is -2.37 V. The overall voltage is calculated by subtracting the oxidation potential of magnesium from the reduction potential of copper: ( 0.34 , \text{V} - (-2.37 , \text{V}) = 2.71 , \text{V} ). Thus, the overall voltage for the redox reaction is 2.71 V.
WHAT IS THE OVERALL VOLTAGE FOR A REDOX REACTION HE HALF REACTIONS AG plus E-ag(S) AND CU(S) CU2 plus 2E?
To determine the overall voltage for the redox reaction involving the half-reactions ( \text{Ag}^+ + e^- \rightarrow \text{Ag}(s) ) and ( \text{Cu}(s) \rightarrow \text{Cu}^{2+} + 2e^- ), we first need the standard reduction potentials. The standard reduction potential for silver (( \text{Ag}^+ )) is +0.80 V, and for copper (( \text{Cu}^{2+} )) is +0.34 V. Since silver is reduced and copper is oxidized, the overall cell potential is calculated as ( E_{\text{cell}} = E_{\text{reduction}} - E_{\text{oxidation}} = 0.80 , \text{V} - 0.34 , \text{V} = 0.46 , \text{V} ). Thus, the overall voltage for the redox reaction is +0.46 V.
