We have also seen that some liquids are better conductors than others are.
Pour the contents of the half cell module into the funnel and then rinse the plastic base with water from a squeeze bottle. Resistance to the flow of charge at a boundary is called the junction potential. Phase boundaries are shown by single vertical lines, and the salt bridge, which has two phase boundaries, by a double vertical line.
The potential of a cell, measured in volts, is the energy needed to move a charged particle in an electric field. The in-lab assignment must be completed by the end of the lab period.
There will be a funnel in the container. Then, carefully pour a small portion of the dilute and basic copper ion solution into well 2. Please click next to continue to the online activity. Refill the original container with fresh distilled water and stir in a few drops of vinegar while watching the ammeter.
