Properties Of Solution

Solubility, S

Max amt. solute that dissolves in a
given amt. of solvent.

Solution [Homogenoues mixture]

Solvent [Gaseous , Liquid]

Solute [Dissolved susbtance]

Types of solution

Unsaturated

Saturated

Supersaturated

Solute - Solvent Interactions

Stronger attraction, Higher S

Pressure, P [Gas - Liquid System]

Higher P, Higher S

Temperature

Solid - Water [Higher T, Higher S]

Gaseous - Water [Higher T, Lower S]

Gas - Liquid Solution [constant T]

S(gas)= k(henry's law)* P(gas)

Liquid - Liquid Solution

Attractive force between substances

Miscible [mix completely]

Immiscible [form 2 layers]

Solid - Liquid Solution

Solvation [molecules solvent surround molecules solute]

Hydration [solute surrounded by water molecules]

Ksp= [A]^m * [B]^n

Qsp > Ksp [precipitate form]

Qsp < Ksp [no precipitate form]

Mass% = mole component in solution x 100
total mole of solution

Mole Fraction, X
XA = nA
nA + nB +nC

ppm = mass of component in solution X 106
total mass of solution

ppb = mass of component in solution x 109
total mass of solution

Molarity (M) = moles of solute
liters solution

Molality (m) = moles of solute
kilograms of solvent

Vapour Pressure

P(solution) = X(solvent)P*(solvent)

2 compound system

Raoult's Law [ideal solution]

P(total)= XP + XP

Boiling Point Elevation

Freezing Point Depression

Osmotic Pressure [pressure to stop osmosis]

Low solute concentration => High
solute concentration

Subtopic
