Electricity From Redox Reactions (HSC SSCE Chemistry): Flashcards

Study of connections between chemistry and electricity

Through chemical reactions

Flow of electrons through a conductor

Oxidation & reduction at separate locations, e⁻ via wire

Approximately 0.5 V

From copper through external circuit to silver wire

$\text{Cu(s)} \rightarrow \text{Cu}^{2+}\text{(aq)} + 2e^-$

$\text{Ag}^+\text{(aq)} + e^- \rightarrow \text{Ag(s)}$

$\text{Cu} + 2\text{Ag}^+ \rightarrow \text{Cu}^{2+} + 2\text{Ag}$

Generates electricity from spontaneous redox reactions
