6. I really wouldn't worry too much about accuracy for this application.

You could buy 80 proof vodka (Polish or Ukrainian please not Russian) dilute it with an equal volume of water and be done with it. It's not clear even what 20% even means, for example, is it by weight, volume or molar.

These differences are close but not identical.

Extractions are more efficient when done serially. Suppose one has 120 ml of an extraction solvent. If one extracts three times with 40 ml, one will obtain more extracting than one time with all 120 ml.

I've done thousands of extractions in my career. I tried not to be a slob about it, but on the other hand, with analytical chemistry being an exception in some cases, there's not much value in being overly meticulous.

20/100 is 20% sl8 Jul 2022 #4

It also depends on the actual proof of the alcohol that you are using. Chainfire Jul 2022 #3

There's chemistry involved too so your suggestion won't work unblock Jul 2022 #5

Well, supposedly 1 liter of water and 1 liter of alcohol mix to form 1.8 liters of solution ... eppur_se_muova Jul 2022 #7

Where are you getting 100% ethanol? Effete Snob Jul 2022 #8

I did not say 100% etoh. Actually I'm using 75% etoh everclear found in the liquor store. nt mitch96 Jul 2022 #11

Yes, you did say that.... Effete Snob Jul 2022 #12
