ViviThe electrochemical series is a list of standard electrode potentials of elements whereas the galvanic series is a ranking of metals in terms of their reactivity in a corrosive environment. The electrochemical series is used to predict the direction of electron flow in redox reactions, while the galvanic series helps identify which metals are more likely to undergo corrosion.

Difference between galvanic series and electrochemical series?
Galvanic series ranks metals based on their tendency to undergo oxidation in a galvanic cell when connected to a standard hydrogen electrode. Electrochemical series ranks elements and compounds based on their standard reduction potentials, indicating their tendency to gain electrons and be reduced. The galvanic series focuses on metals, while the electrochemical series includes all elements and compounds.
What are the differences between galvanic series and emf series?
The galvanic series ranks metals based on their tendency to corrode in a specific environment, while the EMF series ranks elements based on their standard reduction potentials in an electrochemical cell. The galvanic series helps predict which metal will act as an anode and cathode in a galvanic cell, while the EMF series is used to calculate the cell potential of a redox reaction.
Why hydrogen is standard in electrochemical series?
Hydrogen is typically chosen as the standard in the electrochemical series because its reduction potential is defined as zero at standard conditions. This allows for easier comparison of the reactivity of other elements and substances in electrochemical reactions.
Is there a chemical reaction between aluminum and lead?
Aluminum and lead do not undergo a significant chemical reaction when in contact with each other. However, aluminum can form an oxide layer when exposed to air which can act as a barrier between the two metals. It is important to note that prolonged contact between aluminum and lead can result in galvanic corrosion due to their different positions in the galvanic series.
What is a combination of two or more electrochemical cells in series that store chemical energy which transforms into electrical energy?
A battery is a combination of two or more electrochemical cells in series that store chemical energy which transforms into electrical energy.
