Lab 7. Single Replacement Reactions: activity series investigation.

a) https://www.youtube.com/watch?v=AnrRbh1b7I0

In this video you will observe reactions of Fe and Mg metal with Cu2+ ion (CuSO4), and Cu metal with Fe 2+ (FeSO4) and Ag + ion (AgNO3). How does your observations agree with known activity series? When there is a reaction write net ionic reaction for that reaction.

Data Sheet a: fill out boxes what you observed (changes) in the video.

Reagents	Fe (s)	Cu (s)	Mg (s)
Cu2+(aq)	1.	-------	4.
Fe2+(aq)	------	2.	------
Ag+(aq)	-------	3.

In this video six test tubes (1 to 6) containing different metal ion solutions and H+ ions (H2SO4) were treated with three different metals to observe any chemical changes. Write down what you observed in each test tube (they are all properly labeled in the boxes following video description). If there is a reaction write net ionic equation, if no reaction write NR.

Data Sheet b: fill out boxes what you observed (changes) in the video.

Reagents	Ag+(aq)	Cu2+(aq)	Pb2+(aq)	Mg2+(aq)	H+(aq) H2SO4
Cu (s)	1.	X	X	X	5.
Pb(s)	X	2.	X	X
Zn (s)	X		3.	4.	6.
