Which of the following statements is correct?

If $E_{C u^{2 +} / C u}^{0} = 0.34 V$

$E_{H^{+} / H_{2}}^{0} = 0.0 V$

$E_{S n^{2 +} / S n}^{0} = - 0.136 V$

Answer:

Solution:

Concept: A species with a lower standard reduction potential ( $E^{0}$ ) can reduce a species with a higher $E^{0}$ .

Sn ( $E^{0} = - 0.136$ V) can reduce Cu²⁺ ( $E^{0} = 0.34$ V).
