KI solution
 

I have noticed that aqueous dilute solutions of KI develop some kind of
whitish or grayish substance after a few weeks. Anyone know what this
substance is?

Thanks.

You keep it closed and in the refrigerator, right? By dilute, you mean 1%
or so, right? Sea water has more salt than this, and it supports life...

Would dilute KI, (about .5%) support life better than NYC water that's
been exposed to the air for a long time? Or than distilled water that's
been sitting exposed to the air and plastic containers?

Bacteria or algae. Make it concentrated, and dilute as needed.

Probably not. Most likely the medium would only determine *which* classes
of organisms thrived. The "grey mist" would be green or black or ...

I'd say yes. Trace levels of potassium or calcium can greatly
increase the chance of microbial growth in distilled water. Now, the
iodine ion could also be a micronutrient. I suppose microsidal
activity is associated with free iodine in water, not the anion, but I
could be all wrong there.

Please remember that your distilled water contains enough orgainic
material to support microbes, it's the lack of trace elements that
keeps it clean for a few weeks.
