Amount of sodium hydroxide with increased water amount

[Villabacho]

Hey everyone.

I read in Noman’s tech footnotes that it is advisable to increase water amount when using powdered mimosa root bark.

So e.g. going from 1:15 to 1:25 or even 1:30. Bark to water ratio. (I.e. 1.5L water on 50g bark)

Would this also mean that the amount of sodium hydroxide needs to be increased? I suppose not as this should be in relation to the amount of bark. But maybe a slight increase by a few grams?

My molarity calculator said that it would only require 4.4g on 1L of water to reach Ph 13.

So would it be advisable to increase the amount from 50g to 55g Sodiumhydroxide when extracting from 50g powdered bark in 1.5 Liters?

Thank you

There's already a very healthy excess of NaOH, as you've seen from your molarity calcs ... so I'd say you're fine, just use enough water to keep it fluid, or the soup will tend to hold on to some of your NPS.

The NaOH is mostly just basifying the water, there's not much acid in the bark that needs neutralising, as far as I know.

Thank you. That’s what I thought but I would have felt really stupid if that would be the reason for messing it up in the end.

So thanks for you support!!

There's a bit of acidity in the bark but the 1:1 ratio with lye is a sizeable excess of the latter. The difference in water volume is largely unimportant pH-wise, although you may want to add either more lye or some table salt to keep the ionic strength up, which helps the DMT to migrate into the naphtha.
