Calculating the Freezing Point of a Solution: When calculating the freezing point of a solution, one of the important details is called the van't Hoff constant for the solute. The van't Hoff constant, usually denoted by {eq}i {/eq}, equals 1 for non-electrolyte solutes or the number o...
Plug your values into the following equation to calculate the new freezing point of your solution: Freezing point = old freezing point – K x molality Our water example would look like this: Freezing point = 0 – 1.86 x 0.5 = -0.93 degrees Celsius ...
This example problem demonstrates how to calculate freezing point depression using a solution of salt in water. Key Takeaways: Calculate Freezing Point Depression Freezing point depression is a property of solutions where the solute lowers the normal freezing point of the solvent. ...
Calculate the osmolarity of the following: a. 0.1 M {eq}KNO_3 {/eq} b. 0.35 M {eq}Na_3PO_4 {/eq} Osmolarity: An osmolarity is a unit of measurement that measures the osmotic concentration. It shows the number of osmoles per liter of the solution. An osmole is a uni...
If you've ever made ice cream with an old-fashioned churn, you've seen freezing point depression -- denoted Tf -- in action. Freezing point depression is the addition of a solute to lower the freezing point of a solution.
