Notes: Values are given in grams of solute per 100 g of water (g/100 g H₂O). Potassium alum values are reported for the dodecahydrate form (KAl(SO₄)₂·12H₂O), which is the stable crystalline form below ~92°C. NaCl values reflect the extremely low sensitivity of table salt's solubility to temperature — a change of only ~3.3 g over a 100°C range. All data verified against: Seidell, A. (1940). Solubilities of Inorganic and Metal-Organic Compounds (3rd ed.). Van Nostrand.
