Question

You make a solution of a nonvolatile solute with a liquid
solvent. Indicate if each of the following statements is true
or false. (b) The solid that forms as the 
solution freezes is nearly pure solute.

Accepted Answer

Hey everyone, we're told a solution is made by dissolving a non volatile salute in a volatile solvent. Identify the following statement as correct or incorrect. When the solution is frozen, only the solvent freezes while the solute does not. As we've learned in previous lessons, we know that the freezing point of a solution is going to be lower than the freezing point of a pure solvent. And when the solution is frozen, we know that all of it will freeze. If this statement were correct and only the solvent were freezing, the freezing point of the solution would not change. So because of this, we know that this statement is going to be incorrect and we can change this by eliminating the second part of the statement and stating that all of it freezes and this is going to be our final answer. So I hope that made sense. And let us know if you have any questions.
