08. Solving a chemistry problem

6. Based on the phase diagram of H2O-A, answer the following questions:
1) how many crystalline hydrates does component A form? What is their composition?
2) What is the solubility of component A in water at room temperature (20 C)?
3) will an additional amount of the component dissolve in a 60% solution at 10 C?
4) what is the freezing point of x% solution?
5) how much ice will be released from 200 g of X-% solution when cooled to temperature tx?
6) how much water must be added to 50 g of a % mixture cooled to a temperature ty so that the precipitated crystalline hydrate dissolves again?
