swij thinks videoedit may be right about not getting the right ph from using just baking soda.  swij put a dash of a strong lye solution into his already based(somewhat) psuedo/pill mess and proceeded to distill and got alot more to come over.  meanwhile he's going to try and figure out how much lye he can put into how much psuedo for distilling without burning everything up...  anyone have any ideas what % of lye solution would be suitable for a distillation of about 1.5 grams psuedo(that's 24, 60mg. tablets)?

after reading a past post swij thinks he has a better grip on the ph thing but now has another question.  is jetson correct to assume that one can tell when one has gotten all he's going to get from the distillation by frequently checking the ph of the distillate and once the ph is no longer strongly basic the distillation of the base is done?  or would the h2o still be a basic solution also maybe due to excess base?

Possibly

"or would the h2o still be a basic solution also maybe due to excess base?"

The only "base" that comes thru the distillation is pseudo, the pseudo is making the solution basic.  All the NaOH stays in your dist. flask.  However the freebase pseudo should bee mostly separate from the water.

with the baking soda the ph only gets to 7-8 maybe 9 tops.


Yeah, but as you heatit up the BI carb becomes Unicarb (sodium carbonate, washingsoda) with bubbles of CO2:the pH is between11.5 and 12.0:

ideal...

foxy,  that's what jetson was counting on.  the psuedo being the only base coming through and then when the h2o does start distilling the ph should drop due to no base.
