|
|
Term
|
Definition
Occurs when the energy required to separate the ions exceeds the energy released by the combining of the ions with the water molecule |
|
|
Term
|
Definition
Energy required to seperate the ions is less than the energy released by the combing of the ions with the water molecule |
|

|
|
Term
Solid and liquid solutes in Liquid solvents |
|
Definition
Experience an increase in solubility when temperature is increased |
|
|
Term

|
|
Term
|
Definition
Most energetic molecules near the surface of a liquid escaping into the gas phase
Adding an additional solute to the solution, replaces escape points of the orginal solute, therefore reducing vapor pressure |
|
|
Term
|
Definition
Can be used to quantify the change in vapor pressure from introduction of a solute |
|
|
Term
|
Definition
Temperature at which the vapor pressure of the material is equal to the ambient pressure |
|
|
Term
|
Definition
Temperature at which the liquid phase of the material is in equilibrium with the solid phase
Adding a solute to a solution lowers freezing point by interfering in the organization of crystalline structures |
|
