So, I'm making some HP soap and trying to test for done-ness with phenolphthalein. I take a little smidgen out, put a drop of phenolphthalein on it, and it turns pink.
Pink means not done, right? Well I wander off and let it cook some more and come back and the pink on the plate has gone back to clear?? Tried this several more times with the same result...
Does the phenolphthalein degrade/evaporate when it sits out, or do you think my soap is actually done since it's clear now? confused!
There is no zap, but it is definitely pink for some amount of time...
