Question

half-reaction | e° (v)
e²⁺ + 2e⁻→ e | + 0.76
g⁺ + e⁻ → g | + 0.10
j²⁺ + 2e⁻→ j | 0.00
l⁺ + e⁻ → l | - 0.82
which substance acts as the standard in this set of data?
substance g
substance e
substance j
substance l

Explanation:

In standard reduction potential tables, the standard hydrogen electrode (SHE) is typically assigned a potential of 0.00 V. Here, the half - reaction for \(J^{2+}+2e^-
ightarrow J\) has a standard reduction potential (\(E^{\circ}\)) of 0.00 V. This is analogous to the SHE's role as the standard reference, so substance J acts as the standard in this set of data.

Answer:

Substance J
