: [Biofuel] Isopropyl Alcohol supplies - Used to be
Titrationquestion from a Newbie
It seems that hydroponics stores carry very pure isopropyl alcohol as well.
I seem to remember a price of about $40 for one US gallon for the 99.5% stuff,
which is similar to the price you found though.

Guys;
The titration solution is water anyways so what difference is 10% water
gonna make in the IPA? The water is always a problem cuz it makes the
oil want to drop out and unless you've got good agitation I wonder how
accurate the titration really is. I've been wondering what about using
?
Actually, I think anhydrous IPA would be less important.
