Question

Recall our series of chemical interactions from the Experiment: Part I:

3 I- (aq) + S2O82- (aq) 2 SO42- (aq) + I3- (aq)        (1)

I3- (aq) + S2O32- (aq) 3 I- (aq) + S4O62- (aq)       (2)

2I3- (aq) + Starch Blue/Black Complex + I- (aq)   (3)

A.   Characterize I3- and I- as catalyst, intermediate, or neither.

I3-:  

I-:

B.   Identify the molecularity of each of the following.

       Reaction Proposal Molecularity

I- (aq) + S2O82- (aq) 2 SO42- (aq) + I3- (aq)       

2I3- (aq) + Starch Blue/Black Complex + I- (aq)      

Explanation / Answer

I3-    : intermediate

I-   : neither

------------------

1st reaction : molecularity 2

2nd reaction : molecularity 2 (starch is an indicator . It does not react with I3-)
