Q: What processes involve a transfer of electrons between the wire and the solution?


Read this paragraph and choose the correct option from the provided answers:

Electrochemistry is the study of chemical processes that occur at the interface between an electron conductor, such as a wire, and a solution of electrolytes, which is often simply an ionic substance dissolved in water. Electrochemical processes involve a transfer of electrons between the wire and the solution. These reactions can be used to create electrical power, to purify metals, and to carry out a number of useful chemical transformations.

 Choices:

- radioactive

- magnetic

- thermal

- electrochemical


A:
electrochemical
