| Abstract: | In order to find an economical way to prepare sodium nitrate studies have been carried out on the reciprocal system Na~+-NH_4~+-Cl~(-)-NO_3~(-)-H_2O.Though the salt-pair of NaNO_3-NH_4Cl is a stable one,as the phase diagram shows, it is difficult to obtain pure NaNO_3 and NH_4Cl from it,for the solubilities of NaNO_3 and NH_4Cl vary with temperature almost in the same extent. A certain sort of optimum conditions has been approached at which the crystal of NaNO_3 is more heavy with that of NH_4Cl suspending in the solution, thus NaNO_3 can be easily separated from NH_4Cl. |
