SWIM used the 'Dripping HCL onto H2SO4' method. Well SWIM guess it's fine since SWIM never tried other method. But SWIM would like to know, for PSE extraction: when to stop gassing?
This was SWIM's observation:
*Just slightly submerge the tube*
1. Clouds starts to form
(Well it looks more like dripping milk into water)
2. Moooaaawrrr clouds formed
(like... a lot of milk added)
3. The clouds stop forming, and they sort of lumped together.
(No changes seen even if it's gassed)
Sounds familiar?
