The diagram of the ternary system Na+/Cl-, SO4 2- - H2O was established at 150C bymeans of analytical and conductimetric measurements. Three compounds were found in this diagram, which are NaCl, Na2SO4 and Na2SO4.10H2O. The composition (mass%) of the invariant point determined by the towmethods are:NaCl 6.00%; Na2SO4 23.40%.
