Question

critical and thinking based question-:
A battery that consists of a pair of electrode and a person, as an electrolyte, produces a measurable voltage, but only if electrodes are made of different metals.Connect the terminals of the voltmeter to the copper and zinc sheets, and put hand on each sheet. The voltmeter should read about 0.7 V. Other pairs of metals will yield different values, depending on the metal’s relative electrochemical potential. If you replace the zinc sheet by the second copper sheet, and place each hand on a copper sheet, the voltmeter will of course read zero, since two different metals are required for a battery. In order for the battery to function, the surface of your hands must have plenty of ions (this is generally the case). If copper and zinc strips cut from the sheets are placed in a beaker of distilled water, the voltage reading will be zero, showing that electrolyte (ions in solution) is necessary, as well as two different metals, for a battery to work.
1. A Voltmeter in the above context measures

2. Distilled water has no free ions, hence it is *
