SWIM's baking soda batch and the results

[seejaneshred]

SWIM followed the sodium bicarbonate reaction to the T. Resulting liquid was clear and perfect and tasted salty and had the very slightly thick (not water thin) consistency with a ph of 7. But once I put it in the fridge and it totally cooled down, whammo, the famed white power appeared and settled to the bottom. I then filtered the powder out and obtained a clear substance again. This time I had to add vinegar, not much, to get my 7 ph. The resulting liquid was salty and seemed perfect. I took one teaspoon and 30min later nothing. I took another teaspoon and 30min later nothing. I took another teaspoon and 30min later i was falling over, eyes crossing, and passed out snoring on the floor. The last time i did G was when it was legal and i did one cap full and it made me feel good and kinda drunk without all the nasty drunk side effects. a. why do you suppose the white stuff precipitated b. did i just take too much and not wait long enough?

Your response is appreciate.

What was the white powder? It's difficult to be sure, but my first guess would be unreacted sodium bicarbonate. Sodium bicarbonate is not very soluble in water (about 100mg/ml), and cooling it reduces the solubility further to around 75mg/ml. I don't understand why the pH would _increase_ on removal of a base though.

I guess it could also be NaGHB if the concentration was high enough. I believe that the solubility of NaGHB is around 750mg/ml at room temperature.

Which brings me on to the main question: what was the concentration of GHB in the final solution? It's really important to know this for dosing, and it would also help to understand if it could have been GHB crystallising out on cooling.

Also, teaspoons are not really accurate enough for measuring volume. A chap I know uses oral syringes, which are easily and cheaply obtained.

Very true. I doubt it was ghb because of the quantity that remained. Im almost sure it must be the unreacted sodium b. and as you said, when it cools the solubility decreases. SWIM filtered it out and now SWIM has a clear salty solution. The problem is as you said, misdosing. You asked "what was the concentration of GHB in the final solution". How would one calculate this. SWIM is positive there is no GBL left as he does not taste it and the reaction was done in the proper quantities and time. Please inform how to gauge GHB content in liquid. Ill try to search again but I always get sidetracked and end up spending 10 hrs at the computer like everyone else bouncing from thread to thread getting offtrack. Thanks for the help bro and LMK if you can tell me the method on concentration of G. SJS.

The reaction of GBL with sodium bicarbonate (or sodium hydroxide) is very simple. One mole of GBL is hydrolised to produce one mole of sodium GHB.

The molecular weight of GBL is 86.09, and the molecular weight of sodium GHB is 127.09 (figures from Merck). That's a ratio of about 1:1.48, so each gram of GBL will produce 1.48 grams of NaGHB assuming all the GBL reacted.

So multiply the starting weight of GBL by 1.48 to get the maximum possible amount of NaGHB. If you don't know the weight because it was measured by volume, then you first need to multiply the volume by the density, which is about 1.2 grams/ml.
