🧪 Day 47 — Electrochemistry & the Nernst Equation
Passage
A galvanic cell is constructed at 25°C using a Zn(s) | Zn²⁺(0.10 M) half-cell and a Cu²⁺(1.0 × 10⁻³ M) | Cu(s) half-cell. The standard reduction potentials are E°(Cu²⁺/Cu) = +0.34 V and E°(Zn²⁺/Zn) = −0.76 V. A student measures the initial voltage and observes the reaction proceeding spontaneously.
Which is the best estimate of the cell potential under these conditions?
