SWIM followed BLAB. Took the jar out of the fridge today, poured off through a filter, and got a bunch of crystals. Weighed them, ended up with 9 grams, didn't make sense as SWIM only had 5 g of fumarate. Realized that the excess was sodium carbonate, but didn't know how to separate the freebase and sodium carbonate. Ended up warming up the solution that was poured off, since SWIM still had it and dissolving all the crystals back in it and put in freezer. Instead of crystals forming though, ended up with a goo, SWIM doesn't know what to do with it or if it's even right, seems like there isn't really enough of it either. Did SWIM just completely screw up by redissolving freebase and sodium carbonate crystals in the poured off solution, or is there a workaround?
