Consider the following half-reactions and their standard electrode potentials E^\circ :
\(\text{Ag}^+ + \text{e}^- \rightarrow \text{Ag} , \ E^\circ = +0.80 \text{V}\)
\(\text{Cu}^{2+} + 2\text{e}^- \rightarrow \text{Cu},\ E^\circ = +0.34 \text{V}\)
\(\text{Al}^{3+} + 3\text{e}^- \rightarrow \text{Al},\ E^\circ = -1.66 \text{V}\)
\(\text{Cl}_2 + 2\text{e}^- \rightarrow 2\text{Cl}^- ,\ E^\circ = +1.36 \text{V}\)
Which of the following statements is/are correct?
1
\(\text{Cl}_2 \ can\ oxidize\ \text{Cu} \ to\ \text{Cu}^{2+}.\)
2
\(\text{Ag} \ can\ reduce\ \text{Cu}^{2+}\ to\ \text{Cu}.\)
3
\(\text{Cu} \ can \ reduce\ \text{Al}^{3+} \ to\ \text{Al}.\)
4
\(\text{Al} \ can \ reduce\ \text{Ag}^+ \ to\ \text{Ag}.\)
