We recently had an issue in my work place where a water cooler jug contained water with high readings of chlorine (50ppm), there's no foul play suspected, and its been determined that the water jug had residue from the chlorine-based product used to disinfect the water prior to it being refilled.
Anyway, I have to questions, which I have not been able to determine.
1) Someone in our office, who uses the water from the cooler on a regular basis to make his coffee believes that if he had used this water with such a high level of chlorine, that it would have produced Chlorine Gas after being heated up in the coffee maker. Is that possible? Although this may be a taboo question, I thought that it would not be as simple as heating heavily chlorinated water.
2) Does chlorine sink or rise in water?
3) I know this is junk science, but someone decided to test the water with their swimming pool strips, and took a sample of the water home with them on a hot summers day, and tested it about 24 hours later. The bottle was sealed the entire time. How would that effect how the chlorine dissolved, if any?
3a) also the person said that they determined that the water was over 50ppm, as when they tested the water from the cooler, they diluted 2ml of that water (with chlorine) with 18ml of non-chlorinated water, which when tested with the pool strips (which only provide a reading of up to 10ppm), produced a reading of 5ppm, thus, he says that this determined that the water in the cooler was over 50ppm. Junk science, or sound theory?
thanks!
