Question
![The iodine clock experiment, which consists of the following three reactions, is set up
so [S₂O3²] < [S₂O8²]. What would happen if [S₂O3²] > [S₂O3²]?
Reaction 1:
31¯(aq) + S₂O²¯(aq) →→→ I, (aq) + 2 SO²/¯ (aq)
slow
Reaction 2:
Iz (aq) + 2S₂O²¯(aq) → 31¯ (aq) + S₂0² (aq)
fast
Reaction 3:
Iz (aq) + starch → 31¯-starch (bluish black)
fast
Select one:
O a. No bluish black color would form because all the I formed in Reaction 1 would
be converted back into 13.
2-
O b. The bluish black color would be darker because more S₂O3 is present.
2-
O c. The bluish black color would be darker because more S₂O3 is present.
O d. No bluish black color would form because all the 13 formed in Reaction 1 would
be converted back into I.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F79ba64ac-05a9-4fbf-93e3-9626a069652c%2F9f9e97ed-4f60-4119-b3b2-2ea00b8329c6%2F880j41f_processed.jpeg&w=3840&q=75)
