The many student know that batteries product electricity by converting chemical energy into electrical energy but they may not understand the mechanisms that allow this to occur voltaic cell demonstrate some of the chemical reactions that can be used to create electricity students can also personally observed sum up the evidence that the reaction is taking place appeared to sink in copper electrodes to the clamps on the cup been filled the cup with electrolytes such as a see the gases not the didn’t think I and moved into the solution and the think electrode acquires the negative charge think electrode access to the cathode or negative terminal in this cell a positive zinc ions propel positively charged hydrogen ions toward the copperplate the hydrogen ions acquire electrons from this plate and from hydrogen gas students can see the gas bubbles being formed on the copper because the copper electrode loses electrons for the hydrogen it becomes positively charged it acts as the anode or positive terminal in this cell when the play for the seller connected by conducting material an electric current will flow from the copper to the think this cell is capable of producing a potential difference up just over one ball the boat that can easily be measured with a multimeter other electrode materials and electrolytes can also be used and students can determine the most efficient materials they will have fun creating electricity witch this kit the arbor scientific
