10 cards from this deck
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
Cu(s)→Cu2+(aq)+2e−\text{Cu(s)} \rightarrow \text{Cu}^{2+}\text{(aq)} + 2e^-Cu(s)→Cu2+(aq)+2e−
Ag+(aq)+e−→Ag(s)\text{Ag}^+\text{(aq)} + e^- \rightarrow \text{Ag(s)}Ag+(aq)+e−→Ag(s)
Cu+2Ag+→Cu2++2Ag\text{Cu} + 2\text{Ag}^+ \rightarrow \text{Cu}^{2+} + 2\text{Ag}Cu+2Ag+→Cu2++2Ag
Generates electricity from spontaneous redox reactions
