Experimental
...
Setup
...
In
...
this
...
experiment,
...
we
...
filled
...
three
...
1
...
liter
...
graduated
...
cylinders
...
with
...
varying
...
concentrations
...
of
...
Calcium
...
Hypochlorite.
...
The
...
graduated
...
cylinders
...
consisted
...
of
...
a
...
10g/L,
...
20g/L,
...
and
...
30g/L
...
solution
...
of
...
Calcium
...
Hypochlorite
...
solution.
...
The
...
solutions
...
were
...
mixed
...
well
...
and
...
allowed
...
to
...
sit
...
for
...
3
...
days
...
in
...
order
...
to
...
observe
...
the
...
height
...
and
...
weight
...
of
...
precipitate
...
forming
...
in
...
the
...
bottom
...
of
...
each
...
cylinder
...
after
...
each
...
day.
...
The
...
weight
...
of
...
precipitate
...
in
...
each
...
solution
...
was
...
found
...
using
...
vacuum
...
filtration.
...
The
...
contents
...
of
...
each
...
cylinder
...
were
...
poured
...
through
...
a
...
filter
...
and
...
the
...
liquid
...
was
...
vacuumed
...
out.
...
The
...
precipitate
...
left
...
on
...
the
...
filter

paper
...
was
...
then

weighed.

Results
...
&
...
Discussion
...
For
...
the
...
first
...
three
...
days,
...
the
...
height
...
of
...
precipitate
...
in
...
the
...
bottom
...
of
...
each
...
cylinder
...
increased.
...
At
...
day
...
four,
...
the
...
amount
...
of
...
precipitate
...
did
...
not
...
increase
...
from
...
day
...
three.
Using that after 3 days, no more precipitate settles out, gives a good estimate of time to wait before using the calcium hypochlorite solution. Waiting 3 days to use the solution and pouring out only the liquid at the top of solution should decrease the amount of precipitate in the system and help to eliminate clogging.
