>>I did not want to taste it
Why not?  A taste of OA won't hurt you at all!

I did not see a smiley :) at the end of your line so I don't know if 
you were teasing, Randy.  [Prolonged] OA consumption can lead to 
kidney stones according to some sources.  Better not taste it 
especially since one does not know for sure if the concentration has 
changed.  I know, if anything, you'd expected the concentration to 
drop over time but still... better safe than sorry.

>>Inexpensive pHydrion papers will test it quickly for Ph.  To test 
for oxalate ion, just get a little calcium chloride (for melting ice 
on sidewalks), mix a little calcium chl solution with a little 
dissolved OA, and you will immediately get a white precipitate of 
calcium oxalate.

Very interesting.  Will have to try it one day.  Shows who's got a 
good chemistry background. :)

I'd like to understand how much more acidic is OA sugar solution over 
honey (which also contains OA and is acidic).
