WebOct 22, 2016 · It is the ability of the solute to dissolve in a certain solvent or it is the ability of the solvent to dissolve a certain solute . Degree of Solubility is the amount of solute in grams , which dissolves in 100 g of solvent to form a saturated solution at saturated temperature and pressure ( STP ) . Factors affecting solubility The conformation assumed by a polymer chain in dilute solution can be modeled as a random walk of monomer subunits using a freely jointed chain model. However, this model does not account for steric effects. Real polymer coils are more closely represented by a self-avoiding walk because conformations in which different chain segments occupy the same space are not physically possible. This excluded volume effect causes the polymer to expand. WebPhase inversion is a common method to form filtration membranes, which are typically formed using artificial polymers. The method of phase inversion is highly dependent on the type of polymer used and the solvent used to dissolve the polymer.
