Abstract

The solubilities of the quinary system Na

//Cl

-H

O and its two quaternary subsystems

//NO

were studied by isothermal method at 25℃ and their phase diagrams were plotted.In the equilibrium phase diagram of quaternary system Na

//NO

-H

there are one invariant point

three univariant curves and three regions of crystallization with one salt:NaNO

KNO

and Mg(NO
