Question

Would Cl2 be reduced by I- ? Explain.

Answer 1

Yes it would:
Cl2 + 2I- ---> I2 + 2 Cl-
Cl2 + 2e- ---> 2 Cl- E=1.36
I2 + 2 e- ----> 2 I- E=0.54
Since the potential of the Cl couple is higher the I- can reduce Cl2

Answer 2

what does E mean?

Answer 3

@Butchy ?

Answer 4

Sorry I wasn't paying attention , E is standard electrode potential

Answer 5

:D

Answer 6

but we didn't study that in my class

Answer 7

I think the answer is has to do with activity series chart

Answer 8

but I'm not sure how to answer it

Answer 9

Have you hear of Reduction potential ? ( not so sure of the term since english isn't my primary langage)

Answer 10

We studied the activity series in my class

Answer 11

Then you should have some kind of charts, the higher up the charts the stronger the oxydant agent is Chlorine should be higher than iode so that explains why Cl2 would be reduced

Answer 12

oh okay :D Thanks you so much!

Answer 13

@Butchy can you help me with one more question?
