Arrhenius model
acid: produces H ions
base: produces OH ions
Bronsted-Lowry model
acid: proton donor
base: proton acceptor
Lewis mod
acid: electron acceptor
base: electron donor
is something is added to an equation, where does it shift to?
opposite side of
if something is removed from an equation, where does it shift to?
the same side
decrease volume causes the equation to shift to
the side with the least gas molecules
increase in volume causes the equation to shift to
the side with the most gas molecules
pH =
-log[H+]
pOH =
-log [OH-]
