nag sag pms (chemistry) (1 Viewer)

[neuvie]

i know its a stupid question but for chemistry solubility rules mainly in module 8, what does nag sag and pms stand for again? so far ive been memorising the rules are they are without acronyms but kind of still getting confused a lot...i know group 1 is soluble in like everything except LiPO4 and that all nitrates are soluble, as well as specific compounds like PbI2 BaSO4. dont even get me started on the colours of precipitates.

what the fuck is nag sag bag, just look at formula sheet if the compound is on there its insoluble. for colours make ur own system theres often patterns. honestly its kinda just common sense and obviousness like obviously sodium nitrate gonna be soluble and some shit like silver chloride gonna be insoluble

i used nag sag pms castro bear in my prelim exam and got a 0 for all the equation writing because this stupid thing's not entirely correct and misleading in the way its worded
DONT USE
