The reason could be that when these cationic salt of (Na +) phase at the same time, SO42-, NO3-and CH3COO-these anions containing oxygen atoms in all, as the solitary oxygen atoms with electronic solution to the water molecules form hydrogen bonds - , thus increasing their ability to hydration, reduces the activity of water molecules, making aminophylline and sodium nitroprusside response capacity and therefore absorbance with Na2SO4, NaNO3, CH3COONa concentration increase |
