Galvanic (Voltaic) Cells (Leaving Cert Chemistry): Flashcards

Chemical energy to electrical energy

Voltaic cell

Solid conductor that carries electricity

Solution containing ions that conducts electricity

Electrode in solution of its own ions; site of oxidation or reduction

Oxidation

Reduction

Negative

Positive

Maintains electrical neutrality and allows ion flow

From anode to cathode

Approximately 1.1 volts

$\text{Zn} \rightarrow \text{Zn}^{2+} + 2e^-$

$\text{Cu}^{2+} + 2e^- \rightarrow \text{Cu}$

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