Voltaic Cell (5)

The voltage reading, E° cell for the Daniell cell

Formula to determine the cell voltage, E°cell

The voltage of a voltaic cell by using different pairs of metals

The greater the difference of the value of standard electrode potential of pairs of metals, the greater the voltage reading

Operational definition – Chemical cell

Voltmeter shows a reading when different types of pairs of metals are dipped into electrolytes
