How does an electrolytic cell 's electricity established?

• A chemical reaction

• It is pumped into the cell

• It injects itself

• An injected chemical reaction

What kind of electric cell are we going to be working with in this lab?

• electrolytic

• voltaic

• anode

• cathode

For every electrochemical reaction something must be ​ (a)   and something must be ​ (b)   .

• oxidized
• reduced
• cleaned
• increased

What does the charge of an anode depend on?

• Whether it is electrolytic or voltaic

• The charge of the anodes

• If it contains a cathode

• If it oxidizes

What kind of notation is best used for voltaic cells?

• Shorthand notation

• Longhand notation

• Salt bridge notation

• Drawings

TRUE/FALSE

By isolating a reaction in a half-cell it is not possible to calculate what is called a standard reduction potential.

• True

• False

As the reduction potential voltages ​ (a)   , the more readily the species on the left of the equation will ​ (b)   .

• increase
• reduce

A species with relatively large positive reduction potential are strong ​ (a)   agents.

• oxidizing
• reducing
