    I wanted to ask whether in water which contains chlorine and alcohol, chlorine would remove all traces of alcohol in a container such as a test tube and mixed together.


    Would I be able to test for alcohol traces in say my swimming trunks if I got out of a swimming pool that had alcohol spilled on to it from guest in a hotel?


    It's a weird question, I know but it just came up in mind and I seem not to be able to figure out a concrete answer

    As you so eloquently put it though a small amount of alcohol spilled into a whole pool would be below detection limits...
    Is there a known maximum amount of pool water that would make testing for a 1.0 oz alcohol spill untestable? How about a 300 gallon spa? I used to have a spa, and I know alcohol got spilled into it.

    Seems to me, from past excursions into the chemical unknown, that chlorine and ethanol are used to make Chloral Hydrate, a potent sedative and sleep-inducer, widely used years ago. Addiction to Chloral Hydrate was even given a name: "Chlorosis". joc

    "Most pool experts recommend a pool pH between 7.2 and 7.8."

    This is pretty much neutral and not basic enough for the haloform mechanism to be efficient unless a base (such as NaOH)is added, so in a water sample containing chlorine and alcohol at this pH there should be little (or no) reaction and you can test for the alcohol as usual.
    For reason unknown to me, the presence of dissolved chlorine in pool water always causes the Ph to slowly rise, as a result of some part of the mechanism by which chlorine kills bacteria present in the water. This effect seems compounded in arid areas where the make-up water added as needs arise contains the typical alkaline dissolved minerals found in desert areas. jocular

    would the chlorine level be different if it is a saline pool?

    just asking...

    When chlorine dissociates in water, there is an equilibrium between chlorine and hydrochloric acid and hypochlorous acid:

    Cl2 + H2O <----> HCl + HClO

    In water the hydrochloric acid will dissociate into H+ and Cl-. If you add salt (which contains Cl-) by Le Chateliers principle the equilibrium would be expected to shift to the left giving more chlorine. The amount of extra chlorine will depend on hte equilibrium constant for this reaction (I can't be bothered to look it up but I'm guessing the effect isn't large - I could be wrong).

    As far as I know the only way to get a lot of Cl2 from Cl- (the chloride in sodium chloride/saline) is by electrolysis.
    OK....read this three times....I guess this is about as layman as you get? *chuckle* I think I get the general premise!

    Thank you for taking the time to answer my question....Mr. PHDEMON

    So...if I drank it...if I shit myself, I'd actually be cleaning my drawers instead of soiling them?

    Chlorine if memory serves, is a powerful lachrymator (what a word, no idea why it popped into mind), is one of the gases used in WW-I, I believe. Besides causing extreme discomfort initially, it can quickly disable and kill. Hell with the tears! joc

    Clean a bathroom with straight bleach and no ventilation and you will be sick as a dog, even if you are being careful not to put too much anywhere....it is strong stuff!

    Thank goddess you are ok!! Atmosphere to Bethany!
