Describe the phases present in the equilibrium system?
Suppose the system contains 36.0 g (2.00mol) H2O and 58.4 g (1.00mol) NaCl at 25°C and 1 bar.
Table: Aqueous solubilities of sodium sulfate decahydrate and anhydrous sodium sulfate
(a) Describe the phases present in the equilibrium system and their masses.
(b) Describe the changes that occur at constant pressure if the system is placed in thermal contact with a heat reservoir at 30°C.
(c) Describe the changes that occur if the temperature is raised from 25°C to 120°C at con- stant pressure.
(d) Describe the system after 200 g H2O is added at 25°C.
