Galvanic cell made with zinc and copper in grapefruit. This is similar to the first electrical battery invented in 1800 by Alessandro Volta,who used brine (salt water) instead of lemon juice. The lemon battery illustrates the type of chemical reaction (oxidation-reduction) that occurs in batteries. The zinc and copper are called the electrodes,and the juice inside the lemon is called the electrolyte | |
