Reaction of zinc metal and tincture of iodine.
Rewrite the overall reaction: a)Zn (s) + I_2 (alcohol) -> Zn^2+ 2I-
What is the oxidation half-reaction? b)_____________________________
What is the reduction half-reaction? c)_____________________________ _
What is the oxidation number of Zinc as:
Zn (metal)? d)0
Zn^2+ ? e)+2
I_2? f)0
I-? g)1
In this reaction, zinc is h)reduced.
In this reaction, iodine is i)oxidized.
What is the oxidizing agent? j)zinc
What is the reducing agent? k)iodine


Can you help me with the ones I did not do, and tell me if any of the ones I did was wrong and the correct answer?

Oxidation of Zinc: Zn(s) Rightwards Arrow Zn2+ (aq) + 2e-
 
Reduction of Iodine: I2 (s) + 2e- Rightwards Arrow 2 I-(aq)

Net Reaction: Zn(s) + I2 (s) Rightwards Arrow ZnI2 (s)

The oxidation number for zinc is 2, so e)+2

In this reaction, zinc is h) reduced. TRUE ... The next one is true too because iodine loses electrons. The next two are also true...

Good job.
