Explanation:

Define electrochemical terms

We will define each of the 14 electrochemistry terms shown on the worksheet page. The definitions are tailored to a high school chemistry level, focusing on clarity and conceptual accuracy.

Connect to prior knowledge

Using the Electrochemistry knowledge point, we can relate these definitions to fundamental concepts of electron transfer, oxidation-reduction processes, and electrochemical systems.

Answer:

No.	Term	My Definition
2	Electrochemical cell	A device that generates electricity from chemical reactions or uses electricity to drive reactions.
3	Electrolysis	The process of using electrical energy to force a non-spontaneous chemical reaction to occur.
4	Electrolyte	A substance that dissolves in water to produce ions, allowing the solution to conduct electricity.
5	Electroplating	The deposition of a thin metal layer onto a surface using an electrical current.
6	Galvanic cell	An electrochemical cell that uses a spontaneous redox reaction to generate electrical energy.
7	Redox couple	A pair of species consisting of an oxidized and a reduced form of an element.
8	Sacrificial anode	A highly active metal used to protect other metals from corrosion by oxidizing first.
9	Salt bridge	A tube containing an inert electrolyte that connects half-cells to maintain electrical neutrality.
10	Spontaneous reaction	A chemical reaction that occurs naturally under specific conditions without continuous external energy.
11	Standard cell potential	The potential difference of an electrochemical cell measured under standard state conditions.
12	Standard hydrogen electrode	The reference electrode used to measure standard electrode potentials, assigned a value of exactly \(0\text{ V}\).
13	Standard reduction potential	The voltage associated with a reduction half-reaction at standard state relative to the SHE.
14	Voltage	The electrical potential difference between two points, driving the flow of electrons.
