The higher the … WebIt is apparent that the growth rate is enhanced as the impurity concentration is increased and then an asymptotic value of a/ðs has been approached at the higher impurity concentrations, which indicates that the adsorption equilibrium of the impurity on crystal surface is reached and thus the maximum promot ing effect on crystal growth is reached. poly friendly therapistsWebcrystal growth does have an effect on the crystal’s growth and size. Since the precipitants were all four sodium halides, our results have also proven the validity of the Hofmeister Series. The direct ion-protein interactions that occur in crystallization are different for each sodium halide, which produces the different forms of crystals, from polyfrog card
