1) a)
Design a buffer that has a pH
of 8.50 using one of the weak
base/conjugate acid systems shown below.
How many grams of the bromide salt of
the conjugate acid must be combined with how many grams of the weak
base, to produce 1.00 L of a buffer that
is 1.00 M in the weak base?
grams bromide salt of conjugate acid
=
grams weak base =
b) Design a buffer that has a pH
of 4.73 using one of the weak
acid/conjugate base systems shown below.
How many grams of the sodium salt of the
weak acid must be combined with how many grams of
the sodium salt of its conjugate base,
to produce 1.00 L of a buffer that
is 1.00 M in the weak base?

grams sodium salt of weak acid
=

grams sodium salt of conjugate base
=
c)
Design a buffer that has a pH
of 9.43 using one of the weak
acid/conjugate base systems shown below.
How many grams of the sodium salt of the
weak acid must be combined with how many grams of
the sodium salt of its conjugate base,
to produce 1.00 L of a buffer that
is 1.00 M in the weak base?

grams sodium salt of weak acid
=

grams sodium salt of conjugate base
=
