Chap 13 Solutions Flashcards
Unsaturated
Solution with the potential to dissolve more solute
Solubility
The amount of a solute that can be dissolved in a solution at a constant temptress
Super saturated
Solution that has more solute dissolved than possible under normal conditions.
Salvation
The process of a solute separating then being surrounded by solvent
Separating solute has what type of reaction
Endothermic
Separating solvent has what type of retraction
Endothermic
Solvent surrounding solute
Exothermic
Henry’s law effects salvation of
Gasses
C=KP
C= concentration
K= Henries constant
P= pressure
All intermolecular forces
Ionic Covalent Metallic Hydrogen Ion dipole Dipole dipole Ion induced dipole Dipole induced dipole London dispersion forces
Types of concentration units
Percent by mass Molarity Molality Mole fraction Percent by volume Parts per million
Percent by mass
Mass of solute / mass of solution * 100
Molarity
Moles of solute / Liters of solution
Mole fraction
Moles of solute/ moles of solution
Molality
Moles of solute/ kg of solvent
Percent by volume
Volume of solute/ volume of solution * 100
Parts per million
Grams of solute /grams of solvent * 1000000
Entropy (J/Tn)
The measurement of how spread spread an energy within a system is
Miscible
Liquids that can be dissolved in each other partially or completely
Immiscible
Liquids that are non dissolvable in each other
Boiling point
The point when vapor pressure and surrounding temptress become equal
Liquids that are volatile have
High vapor pressure
Colligative property
Properties effected by the proportion of two mixed substances
Four colligative properties
Vapor pressure lowering
Freezing point lowering
Boiling point increasing
Osmotic pressure
Vapor pressure lowering
Volatile / non
Pt =x P
Pt= P1+P2. =. (Px + Px)
Freezing point lowering
DELTA (T) = K m
Boiling point increase
DELTA(T)= Kb m
