Solutions Flashcards
Saturation point
The maximum amount of solute dissolved in solvent. Equilibrium point between aqueous and solid forms of solute.
Rate of dissociation=rate of precipitation
What is the Ksp?
What is it dependent on?
solubility product constant.
Ksp = [+][-] product of concentrations of ions.
dependent on heat and pressure
Ion product
Measure of the current conditions of a solution - snapshot of concentrations of solid and aqueous solute.
IP>Ksp =?
IP=Ksp =?
IP
IP>Ksp = More solute dissolves
IP=Ksp = saturation point
IP
Molar solubility
Molarity of a solute at equillibrium
Molar solubility shortcut:
MX=?
MX2=?
MX3=?
MX=X^2
MX2=4x^3
MX3=27x^4
Common ion effect
Solubility is decreased due to presence of one of the ions in solution.
% composition by mass
mass solute/mass solution x 100
Mole fraction
moles solute/total moles.
Molarity
Moles solute/L solution
Molality
Moles solute/Kg solvent
Normality
equivalents/L solution
