Identify KI(aq) in 1 step

I just realised how easy it is.. Fe(III) is yellow in solution. How could I have missed that? Just add everything to Fe(III), and the one that changes it brown is KI. Trust me to come up with some stupid answer like KI is stored in a dark bottle. Really lame answer.

Fridays are long days, guess it's pretty much as long for all our teachers, so they either come in as lame or as tired as us. Mr Wong was more interested in the Raffles cat outside the window than our overturning ships with high metacentres. Oh yeah, and hk and him were competing with each other to kill flying mosquito-like insects, and ended up wondering how mosquitoes can suck blood of different blood groups and not die. Last week he was giving lame reasons to why the radioactive substance should be kept in a lead container which is contained again in a wooden box, he said it was to let people draw a picture of the radioactive sign on the box. Mr Khoo as usual, got carried away while trying to explain something and ended up somewhere so complex that no one found their ways there. Oh, and Andy got a fishing game set for his birthday, so there was an intense fishing competition among the guys during the 10min break that we got. Not a bad Friday, just lots of work to do this wknd.
