CHEMISTRY COMMUNITY

Can someone please explain the demonstration that happened in class today? I was there but I couldn't see it very well not could I hear much of what was going on.


Thanks!

The demonstration illustrated how a hotdog can act as a conductor for electrons due to its salt and water content. Very much how in a galvanic cell, a salt bridge and external circuit allows current to flow while keeping ion charge balance, a hotdog in contact with an external power source can allow electrons to flow through a diode and light it up.
