Galvanic Cell Types

What is a galvanic cell?

• A galvanic cell is a musical instrument

• A galvanic cell is an electrochemical cell that generates electrical energy from spontaneous redox reactions.

• A galvanic cell is a type of fruit

• A galvanic cell is a type of clothing

Explain the difference between primary and secondary galvanic cells.

• Secondary galvanic cells are more environmentally friendly than primary galvanic cells.

• Primary galvanic cells have a higher energy density than secondary galvanic cells.

• Primary galvanic cells are smaller than secondary galvanic cells.

• Primary galvanic cells are non-rechargeable, while secondary galvanic cells are rechargeable.

Name one example of a primary galvanic cell.

• Voltaic cell

• Leclanché cell

• Fuel cell

• Daniell cell

What is the function of the salt bridge in a galvanic cell?

• To increase the temperature of the cell

• To generate electricity

• To prevent the reaction from occurring

• To allow the flow of ions between the two half-cells

How does a fuel cell differ from a traditional galvanic cell?

• A fuel cell operates without any reactants, while a traditional galvanic cell requires them to function.

• A fuel cell stops working when the reactants are consumed, similar to a traditional galvanic cell.

• A fuel cell does not produce electricity, unlike a traditional galvanic cell.

• A fuel cell continuously receives fuel and oxidant to produce electricity, while a traditional galvanic cell operates until the reactants are consumed and then stops.

Discuss the working principle of a mercury cell.

• The working principle of a mercury cell involves the use of lithium as the cathode.

• The mercury cell works by using copper instead of zinc as the anode.

• The working principle of a mercury cell is based on the chemical reaction between mercury oxide and zinc, where zinc acts as the anode and mercury oxide as the cathode.

• In a mercury cell, the chemical reaction occurs between mercury oxide and aluminum.

What are the advantages of using a lithium-ion battery as a secondary galvanic cell?

• Advantages of using a lithium-ion battery include high energy density, low self-discharge rate, no memory effect, and longer lifespan.

• Shorter lifespan compared to other battery types

• High self-discharge rate

• Memory effect present

Explain the concept of electrode potential in galvanic cells.

• The concept of electrode potential in galvanic cells relates to the potential difference between an electrode and its surrounding solution, indicating the electrode's tendency to gain or lose electrons.

• Electrode potential is the same for all electrodes in galvanic cells

• Electrode potential is a constant value that does not change during the cell reaction

• Electrode potential is not affected by the concentration of ions in the solution

Compare and contrast the features of a galvanic cell and an electrolytic cell.

• Galvanic cells and electrolytic cells both convert chemical energy into electrical energy.

• Galvanic cells convert chemical energy into electrical energy through spontaneous redox reactions, while electrolytic cells use electrical energy to drive non-spontaneous redox reactions.

• Electrolytic cells convert chemical energy into electrical energy through spontaneous redox reactions.

• Galvanic cells use electrical energy to drive non-spontaneous redox reactions.
