what are acids?
proton donors
what is the difference between string and weak acids?
strong acids fully ionise in solution where weak acids only partially ionise
what is the pH equation?
-Log[H+]
what is the Ka equation?
Ka= [H+][A-]/[HA] or [H+]2/[HA]
what does Kw mean?
the ionic product of water
what is the Kw equation?
[H+][OH-]
what are bases?
proton acceptors
what is the difference between strong and weak bases?
string bases are fully ionised but weak bases are partially ionised
what is a buffer?
something which resists the change in pH on addition of small amounts of acid or base or on dilution
what are acidic buffers?
weak acids and a salt of the acid formed from a strong base
what are basic buffers?
weak base and salt of the base formed from a strong acid
what happens when OH- is added to an acidic buffer?
more A- and H2O is formed
what happens when H+ is added to an acidic buffer?
more HA formed
where do anions come from in buffers?
A-
what happens to HA in buffers?
almost all remain unchanged
