Reasoning
Now
that
you
have
an
idea
of
the
colour
of
each
form
of
2,6-dichloroindophenol
and
have
made
observations
during
the
procedure,
it
is
time
for
us
to
conclude
what
is
in
each
layer
at
the
end
of
each
of
the
following
steps
(for
the
basic
salt
form
of
2,
6-dichloroindophenol
call
it
"In-",
for
the
acidic
form
of
2,
6-dichloroindophenol
call
it
"Hin").
Instead
of
making
a
single

argument,
we
are
asking
you
do
to
this
process
for
each
of
steps
3,
5 - 7
and
10-
11.
Your
answers
can
~oi~
but
should
still
include
all
the
components
of a
CER
argument.
Research Question:
In
which layer
is
the 2,6-dichloroindophenol
and
in
whichfonn
is
