Electrochemistry

Question 1

In an electrolytic cell, electrons flow towards the _____

Answer 1

Cathode

Question 2

Oxidation occurs at the _____

Answer 2

Anode

Question 3

Reduction occurs at the _____

Answer 3

Cathode

Question 4

In galvanic/voltaic cells, electrons flow spontaneously from the ____ to the ____

Answer 4

Anode to the cathode

Question 5

What is the purpose of the salt bridge in a galvanic/voltaic cell?

Answer 5

It helps balance out the charge/control charged buildup that occurs when the anode loses electrons (becomes more positive) and the cathode gains electrons (becomes more negative). Since this is the opposite of the intended charges (anode should be neg, cathode should be pos), the salt bridge helps to maintain the normal charges and keep the cell going. It brings anions to the anode and cations to the cathode

It also completes the loop that allows electrons to travel through the circuit

Question 6

When looking at the reduction potentials, the formula with the highest reduction potential will be _____ while the formula with the lowest reduction potential will be _____

Answer 6

Reduced

Oxidized
