Problem- As a KBr and water solution begins to freeze, water molecules will tend to become organized into the pure ice crystal structure excluding the K+ and Br- ions which stay mixed with the remaining liquid water. Eventually, the remaining liquid water will be saturated with KBr and solid KBr will precipitate. Thus the freezing process, if performed slowly, may separate the water from the KBr. What should happen to the freezing point temperature during the early stages of the process? Explain.

I am in need please provide me complete solution for the above problem so I can get right solution
