Question
Chapter 12, Problem 12.15QE
Interpretation Introduction
Interpretation:
The freezing points of sodium chloride and calcium chloride has the compared and the reason why one of these solutions has lower freezing point has to be explained.
Concept Introduction:
Colligative properties depend on the number of solute particles in the solution.
“i” is the number of particles that the solute will dissociate upon mixing with the solvent. With the help of molality of a solution and the number of particles a compound will dissolve to form, it is possible to predict the solution with lowest freezing point.
General steps:
- 1) Each solute has to be labeled as ionic or covalent.
- 2) Determine the number of ions in the formula, if the solute is ionic.
- 3) Multiply the molality of the solution by the number of particles formed when the solution dissolves. This gives the total concentration of particles dissolved.
- 4) Higher the concentration, lower the freezing point.
