how i can determine lsd purity

[kiko]

is it possible to determine the purity of solution that contain lsd? mybe useing ph indector?

A solid dissolved in a liquid would deal with concentration rather than purity, you'd be looking for how much LSD (a mass) would be dissolved in how much water/other solvent (a volume).

And as far as I'm aware there's no simple household way to determine that.

 

[milligrams]

you'd be able to find the concentration if you knew the pH of the solution, and the Ka of LSD. But all I can find is someone says the ph is "about 4" which isn't particularly helpful, because the conc. wasn't stated.
I'm still looking though.


edit, apparently pka(lsd)=7.8



[lsd] =(10^-pH)^2/ 10^-7.8

which would give conc. in mol/litre

then get mass from molar mass.

This assumes the liquid is pure water, and is likely to turn out totally wrong


edit2: so for 100ug/ml, the pH would be 5.65

That only works if there's nothing else in the solution though, and if you know that they've got the ph perfectly balanced...

 

[milligrams]

Yeah true. It would never really work, I just get a bit worked up.. revising for chemistry exams and whatnot

 

[adrian89987]

i mean if you could get gc/ms of course you could

 

[instink]

Could you take an exact volume of the solution (i.e. one mL) and let it evaporate, then with good enough scales weigh what is left over?

 

[adrian89987]

that wouldn't tell you the purity though, just that mass of stuff there, whatever that stuff may be.

eat it and see??

Fair point, but it would still give you a much better idea than none at all
