Lesson 7: Solubility Flashcards
(27 cards)
the extent to which a substance is soluble
Solubility
mass of solute per volume of solvent
Solubility
Solubility rule
Like dissolves like
______ solvents dissolve polar and ionic solutes.
Polar
________ solvents dissolve nonpolar solutes
Non polar
Substances with similar IMFs tend to be ________
soluble in one another
In order for _________ to occur, attractive forces must occur between the solute and the solvent
Dissolution
In order for dissolution to occur, ______________ must occur between the solute and the solvent
Attractive forces
The solution process
- Solvent-solvent interactions - must be overcome to make
room for the solute particles in the solvent - Solute-solute interactions - must be overcome to disperse
the solute particles through the solvent - Solute-solvent interactions - occur as the particles mix
The ____________ IMFs must be stronger than the solute-solute and solvent-solvent IMFs
Solute-solvent
Solubility is _________ on the strength of IMF in the
solute/solvent
Not dependent
Solubility is ________ on the similarity of IMFs present in the solute and the solvent because the IMF formed between the solute and solvent would be stronger
dependent
It is the _________ between the solute and solvent that makes solution possible
strength of the IMF
A molecule is polar if the __________
center of negative charge does not coincide with the center of positive charge
two equal and opposite charges separated in space
Has a dipole
Measure of polarity
Dipole moment
_______ is a composite of the polarities of the individual bonds.
Polarity of a molecule
measure of the ability of the solvent to separate ionic charges
Dielectric constant
Related to polarity
Dielectric constant
high dielectric constant =_____ solvent
polar
w dielectric constant = ________ solvent
nonpolar
Dielectric constant of water
80
H bonds (polar)
Water
