Acid and base Flashcards
(15 cards)
bronsted-lowry model
acid is proton donator
base is proton acceptor
monoprotic
can only donate one proton
strong acid pairs with …
weak conjugate base
properties of strong acid and bases
readily accepts/donates protons
a lot of ions
increased conductivity
self-ionization of water
H2O(l) —-> OH-(aq) + H+(aq)
conjugates
when acid donates -> conjugate base
base accepts -> conjugate acid
buffer systems
resist change in pH
made of; weak acid and conjugate base
and weak base and conjugate acid
smaller Ka value …
weaker acid
smaller pKa value…
stronger acid
types of strong acids
HCl
HNO3
strong bases
NaOH
KOH
weak acids
CH3COOH
weak base
amines
NH3
arrhenius model
when dissolved in water, it will donate H+
what do indicators do
- change colour as the conc of H+ ions changes
- are weak acids or bases
