Unfortunately the really strong ones are missing, so here's a list of mine. I think the word you are looking for is hygroscopic. Since many biomolecules are either polar or charged, water readily dissolves these hydrophilic compounds. 180 degrees means that a drop of water on the surface forms a sphere, which only contacts the solid surface at one tangential point. At 20°C, for example, 177 g of NaI, 91.2 g of NaBr, 35.9 g of NaCl, and only 4.1 g of NaF dissolve in 100 g of water.
