Electrochemistry

Question 1

Anode

Answer 1

Oxidation occurs & more negatively charged electrode in a voltaic cell

Question 2

Cathode

Answer 2

Reduction occurs & more positively charged electrode in a voltaic cell

Question 3

Increasing the concentration of a product (anode) will

Answer 3

Decrease the cell potential

Question 4

Increasing the concentration of a reactant (cathode) will

Answer 4

Increase the cell potential

Question 5

The higher the Ecell

Answer 5

The better an oxidizing agent it is (Likely to undergo reduction)

Question 6

The lower the Ecell

Answer 6

The better a reducing agent it is (Likely to undergo oxidation)

Question 7

Is the reduction reaction spontaneous or nonspontaneous in a positive Ecell?

Answer 7

Reduction reaction is spontaneous in the forward direction

When positive.

Question 8

Oxidizing Agent (Oxidizer)

Answer 8

Reduces by accepting electrons

Question 9

Reducing Agent (Reductor)

Answer 9

Oxidizes by donating electrons

Question 10

Does the mass of an oxidizing ion increase or decrease over time?

Answer 10

The mass decreases over time

Question 11

Does the mass of a reducing ion increase or decrease over time?

Answer 11

The mass increases over time
