5 Questions
What is electrochemistry?
Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change.
How do electrochemical reactions differ from other chemical reactions?
In electrochemical reactions, electrons are not transferred directly between atoms, ions, or molecules, but via an electronically-conducting circuit.
What are the components involved in electrochemical reactions?
Electrochemical reactions involve electrons moving via an electronically-conducting phase between electrodes separated by an ionically conducting and electronically insulating electrolyte.
What is the phenomenon that distinguishes an electrochemical reaction from a conventional chemical reaction?
The phenomenon that distinguishes an electrochemical reaction from a conventional chemical reaction is the movement of electrons via an electronically-conducting circuit.
Give an example of a situation where a potential difference results from a chemical reaction.
An example of a situation where a potential difference results from a chemical reaction is an electric battery or fuel cell.
