Question

Suppose that after measuring the pH of
1.05
M
HCl
solution,
three
drops
(0.20
mL)
of
the

solution
remain
behind
on
the
pH
electrode.

a)
When
this
electrode
is
then
dipped
into
100
mL
of
pure
distilled
water,
show
by

calculation
that
the

pH
of
the
water
is
not
pH
=
7.
b)
Calculate
what
the
pH
would
be
if
the
acid
was
instead,
bromoacetic
acid,
BrCH
2
COOH.

pK
a
=
2.902

c)
Including
HCl
and
bromoacetic
acids
in
(a)
and
(b)
above,
as
well
as
aceti
c
acid

(CH
3
COOH),
chloroacetic
acid
(ClCH
2
COOH)
and
benzoic
acid
(C
6
H
5
COOH),
rank
all
these

acids
in
the
order
of
increasing
strength
and
explain
the
basis
for
your
order.

Why have you made it so difficult to read your question? I worked this yesterday, I think for you.
