lecture 2 Flashcards
what’s a coulomb interaction
ion ion interaction
when are coulomb interactions strongest
when they’re closer together.
shorter inter ionic distances
opposite charges
attract
what’s a non uniform distribution of charge
a shell structure
what’s an ionic cloud
spherical haze of charge around an ion
2 ionic clouds usually overlap.
opposite charges are most likely to be
closer together
what causes shells + ionic clouds
the fact that opposite charges are more likely to be closer together
describe an ionic cloud
ion in the middle
opposite charge on the outside
overlap with another cloud
are clouds good?
yes!! they lower the overall energy + chemical potential energy due to local relaxation.
what does shell size depend on
the concentration // dilution of solute.
aka the ions jt forms
what is the shell length
debye length
for dilute, aqueous solutions,, what is I
the ionic strength of a solution
what is Zi
charge number
what is bi
molality of a species ‘i’
