Based on the state diagram, performing the necessary constructions, determine:
- What type does this system belong to?
- How does the solubility of aniline and water in each other change with decreasing temperature?
- Is the system of composition 60% C6H5NH2 and 40% H2O homogeneous or heterogeneous at 150 0C and what is the composition of the phase (or phases)?
- What changes will occur in the system at 150 0C if the aniline content increases to 90%?
- What changes will occur in the system of composition 60% C6H5NH2 if: a) the temperature is increased to 170 0C; b) decreased to 120 0C?
