Question

Electrochemical reaction occurs in the presence of what

Answer 1

Answer:

The electrochemical process. Interactions of matter associated with the passage of an electric current depend upon the characteristics of the negatively charged electron. ... Thus, an electron conductor must be present as a basic component of any system in which electrochemical reactions are to occur.

Answer 2

Electrons are available in large quantities in a relatively free (mobile) state only in substances called electronic conductors, among which metals are the most important. Thus, an electron conductor must be present as a basic component of any system in which electrochemical reactions are to occur.
