- This was the first day when we found
out what labs we would be doing.
- I went to the library and researched MSDS safety cards on potassium
permanganate and other chemicals that we will be using during
our experiments.
- When at home I went on the web page (lapeer) that has our
labs posted on it and finished the rough copy of the Flow chart
for Composition of a Compound
Friday, May 7th, 1999
- I completed the Flow Chart for Composition
of a Compound
- Continued my research for MSDS, specifically looking for WHIMIS
information to post labels on the chemicals that we will be using,
if they don't have them.
Wednesday, May 12th, 1999
- I set up the basis for the MSDS tables
and began working on them.
Thursday, May 27th, 1999
- I completed most of the MSDS tables
in rough
- I completed typing a coy of the Flow Chart for Composition
of a Compound
- Ivan and me worked on the first copy of the bibliography, having
to go and find all the web sites we used, again.
Friday, May 28th, 1999
- I completed unfinished MSDS tables
and started typing them in good, with the Physical Data in a
separate chart and each chemical on a different page.
Monday, May 31st, 1999
- We gathered materials needed for our
first experiment (Composition of a Compound). Including the Bunsen
burner, protective eyewear and gloves, Erlenmeyer flask, an electronic
balance, a spatula, a test tube and a beaker.
- Alana and me set up the pole and clamp to hold the test tube.
We tested out the electronic balance, just to make sure that
it worked. It did.
- Ivan and me started to gather the chemicals that will be needed
for both of our experiments, in the chemical storage area. We
also started to figure out the WHIMIS statistics of Potassium
Chlorate, Potassium Permanganate, and Sulphuric Acid.
- Also found out that Sulphuric Acid is not spelt like that in
the states, according to this spellchecker and when I was finding
MSDS information for it. It is spelt Sulfuric in the US.

- Dr. Pereyra showed us how to record
the volume of the oxygen being burned while we were doing the
experiment. We were not intending to record this when we first
started.
- We watched Dr. Pereyra amazingly bend a glass rod to help record
volume in our experiment.
- Alana and me gathered a water basin, tubing to direct the oxygen,
and set up the apparatus for the Composition of a Compound lab.
- We began our experiment, Composition of a Compound, at about
2:30 pm, we weighed out 2 grams of Potassium Chlorate, placed
it into the clamp of the heating pole, and took a picture of
the ready apparatus.
- Dr. Pereyra helps us with the first test run of the experiment,
it works out fine.
- I weighed the air in the tube to be about 53mL, and the oxygen
from the Potassium Chlorate began sublimating as soon as the
Potassium Chlorate melted
- We did not use this experiment as one of our results because
we did not have a new full test tube to switch with the old one,
therefore our Volume calculation would be way off.
- On our second attempt, we almost burnt the bottom of the flask
because we had set the gas too high and the Bunsen burner was
to close to the flask, the potassium chlorate solidified in the
flask making it hard to get our.
- On trial 3, the bunsen burner got partly melted and popped
out of the top of the flask.
- On trial 4, we plugged the stopper very tightly into position,
and began the experiment again. Everything was going well, the
Potassium Chlorate was melting nicely and the air in the tube
displaced 54mL of water. We still don't know what went wrong
on this one, we checked all the equipment to check for leaks
or damage, but there was none.
- We didn't have one clear trial done yet, hopefully we will
have more luck tomorrow.
Wednesday, June 2nd, 1999
- We began yet another trial, this is
our 5th for Composition of a Compound. We set everything as perfectly
as we could. The displaced water volume reacted about 50-51mL
again, there was a pause in the oxygen displacement. Then after
a couple of minutes it started to increase rapidly. This time
we were ready with 3 long 50mL test tubes. For some weird reason
the Potassium Chlorate stopped bubbling, but the oxygen continued
to displace the water, and never stopped. We ended the experiment
after about 700mL of water had been displaced. We weighed the
Potassium Chlorate and it was 39.6g
- We continued on with a 6th trial, we continued with the same
steps and after the Potassium Chlorate started bubbling we got
a flask weight of 39.5.
- There are still problems to work out in this test. We think
that the unlimited amount of oxygen was a result of Dihydrogen
Oxide evaporating on contact with the flask.
- The tube leading to the flask acted like a vacuum sucking up
water, up and down. So we unhooked it since we didn't know or
want to know what the result would be if the water made it to
the boiling Potassium Chlorate.
- In our third trial the other day, the stopper in the flask
popped out perhaps because oxygen could not escape through the
pipe easily, thus creating pressure due to an increase in kinetic
energy at constant amount of volume.

- Looked for some more reliable sources
to fill in my N/A (Not Accomplished) MSDS data.
- Finished all other details of Composition of a Compound. Doing
our last trial, with successful results. We are now ready to
make graphs to show the results, also to start the discussion,
and finish the applications for this experiment.
- Relaxed J
Friday, June 4th, 1999
- We set up all the materials needed
for our second experiment, Iron Determination. Having most of
them already at our lab table.
- We meet at school at 3:30, ready to start our second experiment.
We completed 2 trials successfully while Mr. Juzenas and Dr.
Pereyra observed. We had a spill but nobody got any of the substance
on we recovered nicely.
- We are now completely done all of the experiments, all that
is left are the Discussion and the Results.
Monday, June 7th, 1999
- I finished the MSDS in good chart
form, and finished the bibliography for them. It is all WebPages,
with their authors and some with the last update day.
Wednesday, June 9th, 1999
- We all went to the library to discuss
what we had to finish, and finish it. I worked on the graphs
for the results, getting a few tips from Ivan.
- I did the graphs in rough on my computer, there are two Theoretical
Pie Charts, and one for the Mass of the Composition of a Compound,
one for the volume of Composition of a Compound and one for the
Mass of Iron Determination.
Thursday, June 10th
- Finished the graphs in good, and gave
them to Ivan to put in the binder.
- Did some finishing touches to the MSDS sheets, filling in some
previously unknown information.
Friday, June 11th, 1999
- BARBEQUE!!!
Sunday, June 13th, 1999
- Typed up and printed my daily journal
in good. Kept in touch with Ivan on the finishing touches.
Monday, June 14th, 1999
- We handed in our Chemistry ISU, Thank
the Lord! Have a good summer Dr. Pereyra
