Chapter 11 - Electro Chemistry

Question 1

Oxidizing agent

Answer 1

Causes another Atom to undergo oxidation and is itself reduced

Question 2

Reducing agent

Answer 2

Causes another Atom to be reduced it is oxidized

Question 3

Common oxidizing agent

Answer 3

Typically contain oxygen

Question 4

Common reducing agent

Answer 4

Typically contains metal ions or hydrides(H-)

Question 5

Oxidation number

Answer 5

Assigned to Adams to keep track of redistribution of electrons

Question 6

Balanced oxidation numbers

Answer 6

The sum of the oxidation numbers of all Adams present in a neutral compound is zero

Question 7

Half reaction method of balancing oxidation reactions

Answer 7

Each item that is oxidized or reduced is given its own half reaction. These reactions are first determined, and then combined and balanced

Question 8

Spectator ion

Answer 8

An ion that is not taken up in the reaction and who’s oxidation state is not changed

Question 9

Net ionic equation

Answer 9

Shows only the species that are actually oxidized a reduced in the reaction

Question 10

Disproportionation reactions

Answer 10

Atoms oxidation state changes to two different oxidation states

Question 11

Oxidation reduction titration

Answer 11

The measure of the complete reaction of a reacting in at redox reaction
