Which activity is most likely involved with the study of electrochemistry?

combining acetic acid with zinc metal

adding sodium hydroxide to sulfuric acid

placing zinc and copper in an electrolyte

mixing sugar crystals and water in a beaker

The answer is that, from the answer choices, placing zinc and copper in an electrolyte is most likely involved with the study of electrochemistry.

Electrochemistry is the use study of the chemical reactions in relation to electric energy. It comprises the use of electric energy to produce chemical changes and the use of chemical reactions to produce electric energy.

The chemical reactions that produce or use electric energy are carried out in electrolytic cells.

Electrolytic cells consist of a pair of electrodes submerged in an electrolytic solution.

Zinc and copper are good pieces of conductors that work as electrodes in the electrolytic solution. Then, this is the correct answer ...
