Electric Cell Functions and Processes

The video tutorial explains the components and processes within an electric cell, including the roles of electrodes, the salt bridge, and the flow of electrons. It covers the concepts of oxidation and reduction, detailing how electrons are transferred between electrodes. The differences between primary and secondary cells are discussed, along with the changes that occur at the electrodes during reactions. The tutorial emphasizes the importance of understanding these processes for predicting the behavior of electric cells.

What is the primary function of the salt bridge in an electric cell?

• To maintain charge neutrality

• To store energy

• To connect the electrodes

• To provide a path for electron flow

In the context of electric cells, what does reduction refer to?

• Loss of electrons

• Dissolution of metals

• Gain of electrons

• Formation of ions

Which electrode is associated with oxidation in an electric cell?

• Cathode

• Anode

• Electrolyte

• Salt bridge

What distinguishes a primary cell from a secondary cell?

• Secondary cells cannot be recharged

• Primary cells can be recharged

• Primary cells cannot be recharged

• Secondary cells are non-rechargeable

What happens to the anode during the operation of an electric cell?

• It grows in size

• It remains unchanged

• It deteriorates

• It becomes positively charged

What is the result of the reduction process at the cathode?

• Deposition of solid metal

• Dissolution of metal

• Formation of ions

• Loss of electrons

What happens to the cathode as the electric cell operates?

• It remains unchanged

• It grows due to metal deposition

• It deteriorates

• It becomes negatively charged

Which direction do electrons flow in an electric cell?

• From salt bridge to electrodes

• From positive to negative

• From anode to cathode

• From cathode to anode

How can you identify the anode in an electric cell?

• By its connection to the salt bridge

• By its larger size

• By the chemical reaction occurring

• By its positive charge

What is the role of the wire in an electric cell?

• To maintain charge neutrality

• To allow electron flow

• To connect the beakers

• To store energy
