Acid, bases & equilibria Flashcards
What are the definition of Brönsted-Lowry?
- An acid is a substance capable of donating a proton
- A base is a substance of accepting a proton
- Alkali is a base that is soluble in water
Acids and alkalis are exmaple of……
electrolytes
weak electrolytes = partially
what is electrolytic dissociation ?
solutes that slplit into ions when added to a solvent
weak electrolytes = partially
strong electrolytes = completely
meaning of amphiprotic
can accept or donate electrons
what are the 4 types of solvent ?
- amphiprotic
- protogenic
- protophillic
- aprotic
Amphiprotic
Donates and accepts protons
e.g. H2O
Protogenic
Donates protons
e.g. H2SO$
Protophillic
Accepts protons
e.g. NH3
Aprotic
Neither accept or donates protons
what are the 2 types of equilibria
static and dynamic
equation for equilibrium constant K
K= [Products]/[Reactants]
low K = products favoured - weakc acid
high K = reactants favoured - strong acid
Do acids donate or accept ions ?
donate
Do bases accept or donate ?
accept
