Hello all, I am new to these forums so thought I would say hello first! ;D
Currently writing a chemistry EEI for an experiment, it is ment to do with the chemistry around maintaining pools. I have chosen my hypothesis as
The higher the temperature, the quicker the chlorine concentration decreases within the pool water. The 3 samples of water from highest to lowest temperatures will have steadily increasing remaining chlorine concentration within the water.
Now I performed the experiment in the lab and tested each water sample appropriately and found all the concentration levels in parts per million for each water temperature (24C, 4C and 94C). I found the boiling temperature maintained its chlorine more than lower temperatures which was interesting...
I am just having trouble discussing this experiment, usually in an EEI I would relate my findings to earlier work in the same area however this is a standalone assignment, what other things could I discuss in this section as I need a fair few more words to complete this assignment. Thanks for any help

Decomposition takes time. And I also suspect you are using a small concentration.
Odds are pretty good that you just evaporated a lot of water from your hot solution and concentrated the remaining chlorine. It is not going to be easy to get around this evaporation/concentration effect.
