Question
1) Select all of the following that are stronger oxidizing agents than Ni2+
Sn, Fe3+, Ag1+, Br2, Cr3+, Na1+
2) For this question you will need to consult the Standard Reduction Potential Resource in the textbook.
Select all of the following that are weaker oxidizing agents than I2.
Cl2, Cr3+, K1+, MnO41-, Ag1+, Sn2+
3)For this question you will need to consult the Standard Reduction Potential Resource in the textbook.
Select all of the following that are weaker reducing agents than Cr.
Mn2+, Br1-, Cu, H2, Zn, Ni
Explanation / Answer
1. Ni 2+ ---------> Ni Ered = -0.25V
Fe 3+ -----> Fe 2+ Ered = +0.77V
Cr 3+ ------> Cr 2+ Ered = -0.74V
Na+ + e- -------> Na Ered = -2.71 V
Ag+ + e- -------> Ag Ered = 0.80 V
Br2 + 2e- -------> 2Br Ered = 1.06 V
Sn ----------> Sn2+ + 2e- Ered = 0.14V
Oxidizing Agents (may wish to grab electrons from something else and so oxidize the other thing).
Higher up = stronger oxidizing agent
The answer is : Fe3+, Ag+, Br2, Sn
2. Reducing Agents (able to give electrons to something else and so reduce the other thing)
Cl2 (1.36 V),
Cr3+ (-0.74 V)
K1+ (-2.925V)
MnO41- (0.59V),
Ag1+ (0.80V)
Sn2+ (-0.14V)
I2 = 0.54V
Lower down = stronger reducing agent, weaker oxidizing agent
The answer is: Sn2+, K+, Cr3+
3. Mn2+ (-1.52V)
Br1- (-1.06V)
Cu (-0.34V)
H2= 0
Zn = 0.76V
Ni = 0.28V
Cr = 0.74
The answer is: Zn
