This study focuses on measuring the electric current, voltage, and discoloration of BTB in a voltaic cell in
order to explore the principle of electrons flow along the wire and the voltage and electric current of the voltaic
cell in a lack of hydrogen ions. Accordingly, we measured the electric current of the cell when the pH of the cell,
the distance between the two electrodes, the stirring rate, the resistance of the circuit, and the temperature of
the solution were changed, the voltage of the voltaic pile using a NaCl solution, and observed the discoloration
in the voltaic pile using a NaCl and BTB solution. As a result, this research reveals that the movement of hydrogen
ions is considerably important in the mechanism of the voltaic cell quantitatively and qualitatively, and suggests
a new model centered on the reduction reactions of the copper electrode and zinc electrodes.
