Experiments in General Chemistry: Featuring MeasureNet

Third, we have included three new self directed experiments in the second edition of the manual. A self-directed experiment is one in which students write their own experiment to solve an chemistgy problem.

Every third or fourth week during the semester, student teams are required to solve a multi-component problem via a self-directed experiment. Students submit a Procedure Proposal maesurenet weeks before the self-directed experiment is to be performed. Consequently, the Procedure Proposal asks the student teams to answer several focusing questions to help solve the multi-component problem. The procedure proposals are graded, corrected, and returned to each team one week before they perform the self-directed experiment.

Once the self-directed experiment is completed, the student teams submit a Formal Lab Report v vi Preface detailing the experimental techniques used, all data and observations collected, and a thorough discussion of the results and conclusions drawn from the experiment.

We have also relied on Dr. Finally, we have inserted one new Capstone experiment, Experiment This experiment encompasses all techniques, skills, concepts, and principles learned in a two semester general chemistry laboratory course.

Acknowledgments A project of this magnitude requires the assistance of numerous people. We would like to express our deep appreciation and gratitude to the people that have encouraged and assisted us with the production of this lab manual.

We wish to thank our editor Lisa Lockwood. During the development of the second edition, we were assisted by an outstanding editorial assistant Stefanie Beeck. We greatly appreciate her assistance.

We are indebted to his insight and persistence. We were fortunate to have a conscientious, diligent, and hard working group of reviewers. Subsequently, they have started their own company, MeasureNet Technologies Incorporated. They have been instrumental in helping us prepare this manual: We look forward to collaborating with MeasureNet for many years to come. At the University of Georgia, we would like to thank our undergraduate and graduate students in the General Chemistry program.

They have made numerous suggestions and comments that the authors believe will improve the learning experience for the thousands of students who will use this lab manual in the future.

Safety goggles must be worn in the laboratory at all times. Safety glasses are to be worn over eyeglasses. Contact lenses are not permitted in the laboratory. Certain chemical vapors may cause eye irritations when contact lenses are worn. Never eat, drink, chew gum, or smoke in the laboratory. These foods can absorb toxic chemicals.

Never inhale vapors or fumes produced in chemical reactions or from bottled chemicals in the laboratory. Use fume hoods when conducting chemical reactions that produce toxic vapors or fumes. Waft non-toxic or non-irritating fumes toward your nose with your hand when instructed to do so. Never taste chemicals used in the laboratory.

Experiments in General Chemistry: Featuring MeasureNet

Never perform an unauthorized measyrenet i. Never work in the laboratory unless your instructor is present. Never remove equipment, glassware, reagents or other items from the laboratory.

Never return unused chemicals to a reagent bottle. Doing so may contaminate the reagent bottle. Never pour water into concentrated acids. To dilute a concentrated acid, always pour acid slowly into water, while stirring the chemistrh. When inserting glass tubing, a glass funnel, a glass rod, or a thermometer into a stopper, always lubricate the stopper and the glass item with glycerin.

Before attempting this procedure, your instructor will demonstrate the proper technique. Never leave lighted Bunsen burners unattended. Instead, dispose of them in the trash can or specially provided solid waste containers. Report mercury spills from broken thermometers to your instructor immediately.

Because mercury is toxic, it must be disposed of carefully. Never add boiling chips to a hot solution. Adding boiling chips to a hot solution may cause it to boil over rapidly. Short pants, mid-riffs, tank tops, skirts, and open-toed shoes cannot be worn in the laboratory. You must learn to locate and operate all safety devices provided in the laboratory i. At the end of your laboratory session, return all reagents and equipments to their proper places and clean your work area.

Report any laboratory accident, no matter how minor, to your instructor immediately. Never pipet by mouth. Do not blow jeasurenet the last bit of liquid in the pipet. Should chemicals contact your skin, wash the affected area with copious quantities of water and report the incident to your laboratory instructor. After removing chemicals from a reagent bottle, replace the cap on the reagent bottle.

After pouring chemical waste into the Waste Container, replace the cap on the container. Not replacing caps on reagent bottles and waste containers is a chemmistry of Federal Law. Do not directly heat the bottom of the test tube. If chemicals come into contact with your skin, immediately wash the affected area with copious quantities of water.

Fume hoods are used in the chemical laboratory when using volatile or poisonous chemicals. It is permitted to leave a lit Bunsen burner unattended. Always return unused chemicals to a measuernet bottle to avoid wasting chemicals, you will not contaminate the entire reagent bottle. When heating a liquid in a test tube, always point the test feaaturing in a direction away from any other experoments in the laboratory.

Always add boiling chips to a hot solution. The wearing of shorts, tank tops, mid-riffs and sandals is permitted in the laboratory. Drinking soda in the lab is permitted as long as the soda can is at least 10 feet away from all chemicals. I am not required to wear safety goggles while in the laboratory unless I am actually performing an experiment. It is a violation of Federal Law to leave a Waste Container uncapped.

Chemists observe matter by determining, measuring, and monitoring physical and chemical properties of matter. A property is any characteristic that can be used to describe matter e. In this experiment, we will determine the density of liquids and solids. The density of a substance can be used to identify a liquid or experimwnts because density is an intensive property.

Intensive properties are properties that do not depend on the quantity of the substance. For example, gold, which is relatively dense, can be separated from sand, silt, and rock by panning for it in a stream because of its greater density.

Density is the ratio of the mass of a substance to its volume. The density of a liquid can be determined by weighing a known volume of the liquid.

The emasurenet instructor will demonstrate how to weigh an object using a digital balance by the following methods: Chemixtry, sodium chloride solution is added to the graduated cylinder and it is reweighed Figure 2. The volume of sodium chloride solution in the graduated cylinder is recorded by chemiwtry the level of liquid in the cylinder at the bottom of the expeeiments.

Knowing the mass Solids can be regularly shaped cylindrical, cubical, spherical, etc.

The concave or convex surface of a liquid is referred to as the meniscus.
