The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Hansen solubility parameters were developed by Charles M. Hansen in his Ph.D thesis in 1967 [1] [2] as a way of predicting if one material will dissolve in another and form a solution. [3] They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way.

C(NH 2) + 3 + OH − ⇌ HNC(NH 2) 2 + H 2 O. The equilibrium is not complete because the acidity difference between guanidinium and water is not large. The approximate pK a values: 13.6 vs 15.7. Complete deprotonation should be done with extremely strong bases, such as lithium diisopropylamide. C(NH 2) + 3 Cl − + Li + N(C 3 H 7) − 2 → ...
Hydrochloric acid as the binary (two-component) mixture of HCl and H 2 O has a constant-boiling azeotrope at 20.2% HCl and 108.6 °C (381.8 K; 227.5 °F). There are four constant- crystallization eutectic points for hydrochloric acid, between the crystal form of [H 3 O]Cl (68% HCl), [H 5 O 2 ]Cl (51% HCl), [H 7 O 3 ]Cl (41% HCl), [H 3 O]Cl·5H ...
It can also be produced by the addition of hydrochloric acid to a hot, concentrated solution of mercury(I) compounds such as the nitrate: [2] Hg 2 (NO 3) 2 + 4 HCl → 2 HgCl 2 + 2 H 2 O + 2 NO 2. Heating a mixture of solid mercury(II) sulfate and sodium chloride also affords volatile HgCl 2, which can be separated by sublimation. [2]
