Acids, bases and Kw Flashcards
1
Q
What is a Bronsted lowry acid
A
Proton donors
equation: HA + H2O-> H3O+ + A-
state symbols- everything aqueous except “h2O”
2
Q
What is a Bronsted lowry base
A
Proton acceptors
B +H2O -> BH+ + OH-
state symbols: everything aqueous except liquid H2O
3
Q
What do strong acids and base have in common?
A
They both FULLY dissociate in water
4
Q
which way does equilibrium shift depending on whether the acid is strong or weak?
A
For strong acids: equilibrium shifts to the right
For Weak acids: Equilibrium shifts to the left
5
Q
what is H3O + known as ?
A
Hydroxonium ion
6
Q
Kw equation
ionic product of water
A
Kw = {H+} {OH-}
value of kw changes only as temperature changes.
7
Q
What is the equation for pure water?
A
kw= {H+} squared
