Mnemonic for Remembering Salt Solubility Rules
extremely clever mnemonic to remember salt solubility rules.
C A S H n Gia
Read it as "Cashin’ Gia"…how to remember that? well the story is…im a pimp…and gia is my hoe, and i need to get my cash from her. hence…Cashing from gia.
C is clorates, A is acetates, S is sulfates, H is halogens, n is Nitrates, and Gia is Group I A metals. —> THESE ARE ALL SOLUBLE, XCEPT
for S: Ca, Ba, Sr…..just remember the tv network CBS
for H: Ca, Ba, Sr + Happy…whats happy? Hb Ag Pb …mercury, silvr and lead…add a py to the end and all the first letters spell HAPPY
and if its not part of CASHnGIA…its insoluble.
**********
Please note that salt solubility is a complex equilibrium, and it isn’t an either-or phenomenon like a simplified set of rules makes it out to be. Books may differ on how detailed they get about the rules for predicting it, and also on where they draw the line between calling a salt "soluble" versus calling it "insoluble." Keep in mind that the solubility rules are guides to help you predict the relative solubilities of different salts, and take them all with a grain of (ahem!) salt.
