Concept explainers
Interpretation:
The cell voltage measured when the lead electrode is placed in a saturated lead chloride solution has to be determined with the given concentrations.
Concept Introduction:
In all electrochemical cells, oxidation occurs at anode and reduction occurs at cathode.
An anode is indicated by negative sign and cathode is indicated by the positive sign.
Electrons flow in the external circuit from the anode to the cathode.
In the electrochemical cells two half cells are connected with salt bridge. It allows the cations and anions to move between the two half cells.
