Question 1

Electromotive Force

Accepted Answer

The “pull” on electrons from a reducing agent to an oxidizing agent.

Question 2

Redox Reactions

Accepted Answer

Chemical reactions in which electrons are transferred from one species to another.

Question 3

Volts

Accepted Answer

The unit of measure for electromotive force.

Question 4

Oxidizing Agents

Accepted Answer

Species that gain electrons during a redox reaction.

Question 5

Reducing Agents

Accepted Answer

Species that lose electrons during a redox reaction.

Question 6

Spontaneous Reactions

Accepted Answer

Reactions that occur without any external input of energy.

Question 7

What happens on each side of a galvanic cell?

Accepted Answer

On one side, oxidation occurs at the anode, and on the other side, reduction occurs at the cathode.

Question 8

What is the force that electrons feel as they travel through the wire?

Accepted Answer

The force that electrons feel as they travel through the wire is known as the cell potential, which is the same as the electromotive force caused by the redox reaction.

Question 9

How do we calculate standard cell potential?

Accepted Answer

We can calculate standard cell potential (standard meaning 1M concentrations, 298K, and 1 atm) by using the equation E°cell = Ecathode - Eanode.

Question 10

What is the relationship between standard cell potential and reduction potential?

Accepted Answer

The standard cell potential for a cell is the reduction potential for the species in the cathode minus the reduction potential of the species in the anode.

Question 11

What is an anode?

Accepted Answer

An anode is the electrode at which oxidation occurs in a galvanic
