Styrene solubility in water
WebClick to download pdf version. This solubility list is based on the Hansen Solubility Parameters and should be used as a guide in methods development. The nuances of particle solubility in a given solvent should ultimately be investigated by the experimenter during assay optimization and this guide is not a substitute for bench top evaluation. WebWater softening is achieved by percolating hard water through a bed of the sodium form of cross-linked polystyrene sulfonate. The hard ions such as calcium (Ca 2+) and magnesium (Mg 2+) adhere to the sulfonate groups, displacing sodium ions. The resulting solution of sodium ions is softened.
