Solutions And Dilutions Flashcards
Qualitative observations
Changes in colour or physical state
Quantitive measurements
Involves numbers and use SI units
Celsius to kelvin?
+273.5
Importance of therapeutic activities?
Important in formulations and development of new products
API
Active pharmaceutical ingredient
Excipient
any other component of a medicine, other than the
API.
Route of administration
The route of administration of a medicine is the path by which it is taken into the body.
Before an API takes affect?
Before an API can exert any
pharmacological effect, it must
dissolve in a physiological fluid.
It can then interact with the
biological target that plays a role
in the medical condition.
Solution?
a homogeneous mixture of two or more
substances in a single phase.
Solvent?
The component present in the largest amount
Solute
Rest of solution that isn’t the solvent
Dissolved?
Solutions made by the dissolution of the solute in the solvent.
Solubility?
Max quantity a solute can be dissolved in a given quantity of a solvent under specific conditions.
Equilibrium solubility of solute in a given solvent?
- Achieved when the solution exists in equilibrium with excess undissolved solute. The solution is saturated with respect to that solute.
Solubility expressed in terms of concentration?
A quantity of solute for a given quantity of solution.
