Introduction prevents internal short-circuiting of electrons. Internal short-circuiting implies the movement of electrons from the anode to cathode through the electrolyte, which dissipates the chemical energy without providing electrical potential in the external circuit. When the electrolyte is solid, it simultaneously functions as a...
Introduction Vapor that passes the thermometer condenses in the condenser, a double-walled tube that is cooled by water flowing through the outer layer, and drips into the receiver. Before moving on, let us look at benefits and drawbacks to a simple distillation versus a...
