Activity Series & Redox. Metal Reactivity Lab Results. 1. What metal is the most reactive? How do you know?. 2. What metal is the least reactive? How do you know?. 3. Which metal would most likely be found in elemental form in nature? (not in a compound, but just as an element).
1.What metal is the most reactive? How do you know?
2. What metal is the least reactive? How do you know?
3. Which metal would most likely be found in elemental form in nature? (not in a compound, but just as an element)
4. Design an activity series with these 4 metals. Put the most reactive metal at the top and the least reactive on the bottom
Will a reaction occur between Li & AuCl?
What is the metal in AuCl?
Is Li+ more reactive than Au+?
Li + AuCl LiCl + Au
Is the free element above the element in the compound?
Al(NO3)3 + Ag
CaCl2 + Na
No – no reaction
LiNO3 + Ag
Example: Formation of pure Cu Metal
Cu 2+ + 2 e- Cu
copper II electrons copper
ion (ore) metal
Where would you find a Cu2+?
Formation of Copper II ions
Cu Cu 2+ + 2 e-
copper copper II electrons
Which copper is in a compound?
Which is the pure copper?
If metal chemically combines with oxygen, can it remain neutral?
2+Identify what is being oxidized and reduced.
Oxidized is loss of electrons = becomes more positive
Reduction is gain of electrons = # is reduced
When do elements have a charge?
Elements have a charge when in a compound.
