Thus, it is important that students of chemistry do experiments in the laboratory to more fully understand that the theories they study in lecture and in their textbook are developed from the critical evaluation of experimental data. The laboratory can also aid the student in the study of the science by clearly illustrating the principles and concepts involved. Finally, laboratory experimentation allows students the opportunity to develop techniques and other manipulative skills that students of science must master. The faculty of the Chemistry Department at UC Davis clearly understands the importance of laboratory work in the study of chemistry. The Department is committed to this component of your education and hopes that you will take full advantage of this opportunity to explore the science of chemistry. A unique aspect of this laboratory program is that a concerted effort has been made to use environmentally less toxic or non-toxic materials in these experiments. This was not only done to protect students but also to lessen the impact of this program upon the environment. This commitment to the environment has presented an enormous challenge, as many traditional experiments could not be used due to the negative impact of the chemicals involved.

  • Formula of a Copper Chloride Hydrate
    Determining the Percent Composition and Formula of a Copper Chloride Hydrate Overview: The mass percents of Cu, Cl and H2O in a compound are determined by separating and massing the three components. A major emphasis of laboratory work for a chemist is determining the composition of a compound. There are many tools (such as, chromatographic separation and spectroscopy) available to aid the chemist in determining chemical composition. As you study chemistry at Wofford you will be exposed to many of these analysis techniques. In this lab you will become familiar with the techniques of sample heating, vacuum filtration, and the proper handling of strong acids. We will start with a copper chloride hydrate of unknown composition (CuxCly • z H2O). We will sequentially separate the components of water and copper, leaving behind a solution of chloride ions. The water will be removed by heating. Hydrated salts quickly lose their waters of hydration during heating. Reweighing the sample after heating will reveal the mass of anhydrous (without water) CuxCly, and thus the mass of water initially in the compound. Dissolving the salt in water and reacting the copper ions with a more reactive metal will separate out the copper. The copper collected in this way is then massed. The mass of chloride present in the compound is obtained by difference. Experimental Procedure: Removing the H2O: • Turn on the hotplate located between the desks or in the hood and adjust to a setting of 5 or 6. • Clean, dry, and weigh a small ceramic crucible. • Weigh out between 1 and 2 grams of the blue copper chloride hydrate into the crucible.

A Publication of American Chemical Society Joint Board-Council Committee on Chemical Safety. 7th Edition-Vol 1 Safety in the Chemistry Laboratory General • All students must pass the Safety Quiz and sign a Safety Agreement before working in the lab. • State and Federal law require the use of splash proof safety goggles by anyone working in a chemical lab. No student will be allowed to work in the lab or weighing room without wearing the department approved splash-proof safety goggles with side shield, lab apron/coat, and closed toe shoes. There will be no exception to this rule. • You will be doing lab experiments that require hazardous chemicals. To ensure a safe chemistry lab you need to follow : o all safety rules given , o the safety DVD, and o all written and verbal instructions given for each experiment. • All safety rules will be strictly enforced. Ignoring or failing to follow any safety rule or instruction will result in your being dismissed from the lab. Safety Equipment Know the locations/operations and use of the following emergency equipments: 1. Fire extinguisher is stored in a compartment attached to the wall. 2. Red fire alarm is on the wall at eyelevel next to the fire extinguisher 3. Fire blanket is stored inside a labeled red box attached to the wall next to the fire extinguisher. The blanket is to be used on clothing that caught fire. The blanket can also be used to cover a shock victim. 4.

  • 7A. Empirical Formula
    NAME PERIOD DATE 7A. EMPIRICAL FORMULA (Colorimeter Version) Initial Question A major emphasis of laboratory work for a chemist is determining the composition of a compound. There are many tools, such as chromatographic separation and spectroscopy, that aid the chemist in determining chemical composition. By keeping track of mass and breaking a compound into its component pieces, the pieces can be measured and the composition determined. How do you discover the formula for an unknown substance? Materials and Equipment Model 1 Hot plate, 1 per group, or an oven for the class Unknown copper hydrate, 1.0–1.5 g Crucible and cover Balance (1–2 per class) Crucible tongs Model 2 Data collection system Volumetric flask, 100-mL Colorimeter sensor Unknown copper hydrate, 1.0–1.5 g Sensor extension cable 0.10 M Copper(II) chloride (CuCl2·2H2O), 60 mL Graduated cylinder, 25-mL Distilled water, 25 mL Safety Add these important safety precautions to your normal laboratory procedures: Do not look into a hot crucible. Hot material may be ejected. Do not touch chemicals with your hands. PASCO / PS-2828 93 7A. EMPIRICAL FORMULA / STUDENT HANDOUT Getting Your Brain in Gear 1. In this lab, you will be heating a hydrate to remove the water. Label the appropriate molecules in the before-heating and after-heating diagrams below with “Hydrate,” “Anhydrous salt,” and “Water.” 2. Write a mathematical equation that would show the relationship between the mass of the hydrate, the mass of water lost, and the mass of the anhydrous salt. 3. There are two possible ionic compounds that can be formed by copper and chlorine.

  • Chemistry 2A Lab Manual Standard Operating Procedures Fall Quarter 2017
    Chemistry 2A Lab Manual Standard Operating Procedures Fall Quarter 2017 Department of Chemistry University of California - Davis Davis, CA 95616 Student Name Locker # Laboratory Information Teaching Assistant’s Name Laboratory Section Number Laboratory Room Number Dispensary Room Number 1060 Sciences Lab Building Location of Safety Equipment Nearest to Your Laboratory Safety Shower Eye Wash Fountain Fire Extinguisher Fire Alarm Safety Chemicals Revision Date 08/31/2017 Preface Chemistry is an experimental science. Thus, it is important that students of chemistry do experiments in the laboratory to more fully understand that the theories they study in lecture and in their textbook are developed from the critical evaluation of experimental data. The laboratory can also aid the student in the study of the science by clearly illustrating the principles and concepts involved. Finally, laboratory experimentation allows students the opportunity to develop techniques and other manipulative skills that students of science must master. The faculty of the Chemistry Department at UC Davis clearly understands the importance of laboratory work in the study of chemistry. The Department is committed to this component of your education and hopes that you will take full advantage of this opportunity to explore the science of chemistry. A unique aspect of this laboratory program is that a concerted effort has been made to use environmentally less toxic or non-toxic materials in these experiments. This was not only done to protect students but also to lessen the impact of this program upon the environment. This commitment to the environment has presented an enormous challenge, as many traditional experiments could not be used due to the negative impact of the chemicals involved.
