Salt bridge

Question 8

Device used to measure the voltage delivered by a spontaneous redox reaction

Answer 8

Voltmeter

Question 9

Provides the needed voltage to drive a non-spontaneous redox reaction

Answer 9

Voltage source

Question 10

Utilizes a spontaneous reaction to generate electricity: thus the cell potential in this electrochemical cell is positive.

Answer 10

Voltaic (Galvanic) cell

Question 11

The cell potential in this electrochemical cell is negative, then a voltage source is used to drive the non-spontaneous reaction

Answer 11

Electrolytic cell
