ANALYTICAL METHODS [OSMOMETRY] Flashcards
1
Q
This is the measurement of osmolality of an aqueous solution such as serums, plasma, or urine.
A
Osmometry
2
Q
This is based on the principle based on measuring changes in colligative propertoes of a solution that occur owing to variation in particle concentration.
A
Osmometry
3
Q
What are the examples of colligative properties of a solution?
A
- Vapor Pressure Lowering
- Boiling Point Elevation
- Freezing Point Depression
- Osmotic Pressure
4
Q
What are examples of osmotic particles?
A
- Glucose
- Urea Nitrogen
- Sodium
5
Q
This is the most commonly used method for measuring changes in colligative properties of a solution.
A
Freezing-point Depression Osmometry
6
Q
The principle is that the addition of solute molecules lowers the temperature at which a solution freezes.
A
Freezing-point Depression Osmometry
7
Q
What is the formula for the FDO when compared with a pure solvent?
A
1.0 mOsm/kg solution = 0.00186 C
