How to test CCl4?
If I have a container with 50 mL of liquid in which approximately 70% (by volume) is water and the remaining 30% is presumably CCl4,how can I test the
immiscible liquid at the bottom to confirm that it's CCl4?
While I'm on the subject, how can I discard this liquid responsibly - if, indeed it happens to be CCl4?

I forgot to mention that I don't have any iodine. Would solubility of sulfates provide any clues?

If it removes those stubborn stains, it's probably CCl<sub>4</sub> 
[edit] Don't forget; its toxicity is high especially to the liver . . .

That it does (well, I've only tested it on some mildew). Are there any other non-polar, relatively stable compounds of chlorine aside from chlorofom?
There's some conflicting data on the net concerning CCl4's toxicity. Does anyone have any references to tests that have been conducted or studies of
humans that have been exposed?

Thanks HN. I've been treating it like a carcinogen, just in case.
Is there any easy way to convert it to something safe(r) that can be flushed down the drain? I realize it's a small amount but I want to include a
method of safely disposing of it in my notes.

To dispose of very small quantities of toxic or carcinogenic solvents, one method is that if you have access to a wide open space, pour the solvent on
a piece of paper towel, and let it evaporate outside in the sun. If it's volatle like CCl4, it shouldn't take much time. Keep away from people and
pets if you do that.

At one time, its fairly agreeable smell was pervasive on the high street around laundries and such - it was also the main ingredient in dab-it-off,
the stain remover . . .

CCl4 is obviously not politically correct. That means you should seal it up in a bottle and put it on your shelf to enjoy!
I agree with evaporating into the atmosphere for small scale. You wouldn't want to use it for an experiment, DCM or chloroform could be used in almost
all cases.

Thanks for the suggestions. I'm going to pour it on some oil/grease stains on the driveway during the hottest hour of the day so it'll evaporate
quickly. I'm not 100% sure that CCl4 is what's in the jar but better safe than sorry. Like lighting a fuse.... pour and run. No pets or people
downwind.

Fill a measuring cylinder or small volumetric flask and determine the weight difference. Or measure its boiling point.
