What Is The Electrochemical Series

The video explains the electrochemical series, a ranking of metals based on their ability to lose electrons, and how it affects voltage production. Hydrogen's electrode potential is used as a reference point. The series helps predict electron flow between metals and displacement reactions. Redox reactions, involving simultaneous oxidation and reduction, are also discussed.

What determines the voltage produced by different combinations of metals in the electrochemical series?

• The distance between metals in the series

• The size of the metal atoms

• The temperature of the environment

• The color of the metals

Why is hydrogen's electrode potential significant in the electrochemical series?

• It is the highest potential in the series

• It acts as a reference point for other potentials

• It is the least reactive element

• It is the most reactive element

In the electrochemical series, electrons move from a metal with a more negative potential to one with a more positive potential. Which of the following pairs follows this rule?

• Copper to Zinc

• Mercury to Lead

• Hydrogen to Potassium

• Potassium to Hydrogen

What happens when a more reactive metal is placed in a solution with ions of a less reactive metal?

• The more reactive metal dissolves

• No reaction occurs

• The less reactive metal displaces the more reactive metal

• The more reactive metal displaces the ions of the less reactive metal

Why does an iron nail get coated with copper when placed in a copper sulfate solution?

• Copper is more reactive than iron

• Iron is more reactive and displaces copper ions

• The solution is too acidic

• The nail absorbs copper ions
