Arrhenius Theory
|
anything that is dropped in water and forms H3O+ is an acid
anything in water that forms OH- is a base |
|
|
Bronsted Lowry theory
|
anything that donates a proton (H+) is an acid
anything that receives a proton is a base |
|
|
conjugate acid
|
thing that receives from the acid
|
|
|
conjugate base
|
the former acid that lost its proton and is now not an acid
|
|
|
the stronger the acid
|
the weaker it's conjugate base
|
|
|
the stronger the base
|
the weaker its conjugate acid
|
|
|
for a reaction to reach completion
|
the reactants must be stronger than the products
|
|
|
Lewis Theory
|
something that accepts an electron pair is an acid
something that donates an electron pair is a base YOU NEED TO ACTUALLY DRAW THE ELECTRON DOT STRUCTURE |
|
|
PH=
|
-log[H+]
|
|
|
POH=
|
-log[OH-]
|
|
|
PH + POH=
|
14
if you know one you know the other |
|
|
Titration problems
|
Macid x Vacid = Mbase x Vbase
because Ma x Va= moles of acid Mb x Vb= moles of base |
|
|
buffer solutions
|
keep the PH neutral
weak acid + weak acid's salt --> Buffer |
|
|
Salts
|
ionic compound with positive ions other than H+ ions and negative ions other than OH- ions
Acid + Base--> salt + water |
|
|
Amphoteric substances
|
something that can donate or receive a proton
can be an acid or a base |
|
|
acid rain
|
when oxides of sulfur and nitrogen combine with the air to make H2SO4 and HNO3
|
|
|
strong acids
|
HCl HBr HI HNO3 H2SO4 HClO4
|
|
|
strong bases
|
LiOH NaOH KOH RbOH CsOH
