draw the HA-H2Ophase diagram (T vs.XHA) (left side isH2O, right side isHA) for the HA acid that is a weak acid and gives 3 differenthydrate forms when hydrated with water.
-melting point of HA is -81.7°C
-congruent melting point of HA.H2O is-33.8°C
- 2HA.H2O melts incongruently and peritectic point isobserved at -74.1°C
-congruent melting point of 4HA.H2O is-97.6°C
- eutectic points are: -70°C, -101°C and -110°C
