GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION
Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs
Frank J. Horgan Filtration Plant
The Frank J. Horgan Filtration Plant is located Southeast of Toronto on
the shores of Lake Ontario (See map). Its purpose is to provide safe drinking
water to our taps by filtering the water. The water is gathered from Lake
Ontario. This plant has
Animals In The Research Lab
The use of living animals is an important way to solve a medical problem.
Researchers continually seek other models to understand the human organism,
study disease processes, and test new therapies. In seeking quicker and not so
expensive ways to look for biologic
The purpose of this lab is to see hoe chemists use the concept of moles to describe what happens in a chemical reaction. In this experiment we mixed weights of pure elemental iodine and allowed them to react with zinc until all of the iodine has been consumed. I think that we will be able to
Identification of a Copper Compound by Percent Mass
Unknown Compound: #9
The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this, the mass of copper in the unknown was calculated and then divided by the mass of the whole compound t

Mass Relationships in Chemical Reactions Lab
The aim of this experiment is to react Sodium bicarbonate with Hydrochloric acid and to determine the reaction’s percent yield by looking to the mass (amount in mol used in calculations) of one of the products, Sodium chloride.
Title: Phases and Eclipses of the Moon
Purpose: The purpose of this lab is to demonstrate the different phases of the moon during its revolution around the earth and also to display solar and lunar eclipses.

Titration of and Acid With a Base
Purpose: The purpose is to use burets to accurately measure volumes of a solution. I will also be learning how to learn to recognize the end point of a titration. I’ll be learning to describe the procedure for standardizing a
Through trial and error my class and I have learned that screwing around
and misbehaveing in lab not only results in multiple page papers, but can also
be harmful, dangerous, and costly to our teacher and school.
There are many rules or "protocols" that should be followed in a
