Concept introduction: In an electrochemical cell, the energy is expressed in voltage. The overall voltage is measured as the difference between the potentials of the half cells.
Answer to Problem 1E
In an electrochemical cell, electrons are transferred from the more active metal to the less active metal.
Explanation of Solution
The activity series of metal in the order of increasing reactivity is,
Gold < Silver < Mercury < Bismuth < Antimony < Hydrogen < Lead < Tin < Nickel < Cobalt < Cadmium < Iron < Chromium < Zinc < Manganese < Aluminium < Calcium < Strontium < Barium < Lithium < Sodium < Potassium
This reactivity series implies that a metal with high reactivity can displace a metal with a low reactivity.
So, in a electrochemical cell, electrons are transferred from the more active metal to the less active metal.
The electrons are transferred from the more active metal to the less active metal in a electrochemical cell.
