e.g. Li2S Na2S CaS K2S SrS (NH4)2S BaS (i.e. alkali and most alkaline earth cations and ammonium) Hydroxides of the alkaline earth metals (Group 2) become more soluble as you move down the group i.e. Ba(OH)2 is more soluble than Ca(OH)2, – which is more soluble than Mg(OH)2. for Solubility (from Cornell University - Chemistry Department) (Sing to Rhythm of 99 Bottles) Potassium, sodium and ammonium salts, Whatever they may be, Can always be depended on for solubility. When asked about the nitrates The answer is always clear, They each and all are soluble, Is all we want to hear. Most every chloride's soluble At least we've always read Save silver, mercurous mercury And (slightly) chloride of lead Every single sulfate Is soluble, 'Tis said 'Cept barium and strontium And calcium and lead. Hydroxides of metals won't dissolve That is, all but three Potassium, sodium and ammonium Dissolve quite readily. And then you must remember That you must not "forgit" Calcium, barium, strontium Dissolve a little bit. The carbonates are insoluble,
