acid base Flashcards
bronsted lowry acid
an acid loses a proton
bronsted lowry base
a base gains a proton
any species that has a hydrogen can potentially act as a/an ____.
acid
any species that has a lone pair can potentially act as a/an ___
base
conjugate base:
an acid loses a proton to form its conjugate base
conjugate acid:
a base loses a proton to form its conjugate base
remove an H from acid to form
conjugate base
add H to base to form
conjugate acid
strong acid has a strong tendency to
lose a proton
weak acid has little tendency to
lose a proton
strong acid has a ___ conjugate base
weak (has little affinity for the proton)
weak acid has a ___ conjugate base
strong (high affinity for proton)
strong acid: ___ favored at equil
products
weak acid: ____ favored at equil
reactants
Ka measures:
the degree to which an acid dissociates in a solution
relationship between acidity and Ka
stronger acid = higher Ka
relationship between acidity and pKa
stronger acid = lower pKa
what is the most organic acid
carboxylic acid
alcohols have a ___ group
-OH
what are amines?
compounds that result from replacing 1 or more of the hydrogen bonded to the ammonia with a carbon containing substitute
most common organic base
an amine
H2O and HCl
which will act the acid/base?
HCl is the stronger acid (lower pKa) so it will lose the H+
equilibrium favors the formation of the __ acid
weaker
Arrhenius acid
increases H+ concentration of aqueous solution
Arrhenius base
increases OH concentration of aqueous solution
Lewis acid
electron acceptor
Lewis base
electron donor
pKa of weak acids
3-5
