Module 5: Solutions Flashcards
Test 2
What does (aq) mean?
Aqueous
In water
T/F: Ions are always in aqueous solutions
T
Differentiate between: Solute; solvent; solution
Solvent- major component of mixture (water/liquid)
solute- minority component of mixture (thing being dissolves)
solution- homogenous mixture of 2 substances (or more)
Polar bonds are more ______ soluble
water
Nonpolar bonds are more _______ soluble
lipid
Increasing disorder means
Increasing entropy
What is entropy?
Measurement of energy randomization
Disorder
T/F: Increasing entropy makes a more favorable process?
T
T/F: All ionic compounds are soluble in water?
F
What does solubility depend on?
The tendency to mix (entropy)
Intermolecular forces (similar)
Why can you overdose on vitamin E?
Its so lipid soluble, therefore our body stores it longer (accumulation). It can become toxic because we dont excrete it the same.
Define: Saturated
A solution with the max amount of solute a solvent can hold
No more solute can be added unless heated
Define: Unsaturated
A solution where you can add more solute to a solvent
More solute will dissolve
Define: Supersaturated
A solution that holds more than the max solute dissolved (usually by heating)
Unstable solution
More solute =
more concentrated
