Question

Electrochemistry is defined as a science that deals with the relation of electricity to chemical changes and the interconversion of chemical and electrical energy.

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

neutralizing an acid with a base

producing a gas using a metal and an acid

placing two metal strips in an electrolyte

making a solution from crystals and water

Answer 1

Placing two metal strips in an electrolyte.

Answer 2

placing two metal strips in an electrolyte

Step-by-step explanation:

In electrochemistry we study the conversion of electrical energy to chemical and chemical energy to electrical energy.

If we place two metal strips in an electrolyte, based on their electrode potential values, one of the metal strip will act as anode and other as cathode. The anode will undergo oxidation and cathode will undergo reduction. This can be like we pass electric current and electrolysis occurs or due to migration of electron electric current is produced. Both the cases will be studied in electrochemistry.
