Draw temperature composition phase diagram for binary System?
Use the following information to draw a temperature-composition phase diagram for the binary system of H2O (A) and Na2SO4 (B) at p = 1 bar, confining t to the range 20 to 50 C and zB to the range 0-0.2. The solid decahydrate, Na2SO4. 10H2O, is stable below 32.4°C. The anhydrous salt, Na2SO4, is stable above this temperature. There is a peritectic point for these two solids and the solution at xB = 0.059 and t = 32.4°C. There is a eutectic point for ice, Na2SO4 .10H2O, and the solution at xB = 0.006 and t = 1.3°C.
