Subject: heating samples of dissolved iodised salt at different temperatures

hi i was wondering if after heating samples of dissolved iodised salt at
different temperatures the trend of the decrease of iodine content will be a
straight line or a curve. i cant seem to find anything on the internet about
this and need an indicator of how my titration results should be looking as i am
worried that my experiment may not be indicative to what i am supposed to
finding. my temperatures are 25 50 60 70 and 80 degrees celcius
thanking you
