v Introduction CHM151LL forms an essential part of your chemistry learning experience. The experiments you will perform should illustrate and reinforce the concepts introduced in your lecture class. This laboratory course will also engage you in activities to help you develop accurate and precise measurement skills, sharpen observation and manipulation skills, familiarize you with some basic equipment and lab operations, and strengthen your inductive and deductive reasoning abilities. You can make the most of your lab experience by coming to lab well prepared and on time, and by following the regulations and safety precautions given below. Laboratory Practice Regulations 1. Read and follow the safety rules. 2. Reagents: a) Never remove reagent bottles from the supply area. b) Take only the minimum quantity of reagent from the stock bottle. Store liquids in a clean test tube, flask, or beaker; store solids on a watch glass or in a small beaker. Label storage containers with your name, the date, and the chemical name or formula of the reagent. c) Use a clean spatula or the dedicated spatula for dispensing solids. d) Never insert a pipette or eyedropper into a stock reagent bottle. Instead, transfer the liquid to a clean beaker and pipette or deliver from the beaker. e) Never return unused chemicals to the stock bottle. f) Keep the stock-bottle stoppers clean and replace them after use. 3. Dispose of excess reagents or reaction products as directed by your instructor. Never use the sinks for disposal of waste lab chemicals. 4. Deionized water is expensive. Use it only for the final rinsing of glassware and for making up aqueous solutions. 5. Plan to work individually unless specifically instructed to do otherwise. 6. Note the location of the MSDS binder, exit doors, emergency eyewash, emergency shower, fire alarm, and fire extinguishers in your laboratory. 7. If a chemical gets in your eyes, in your mouth, or on your skin, rinse the affected area with plenty of cold water. Do not hesitate about this, whether it involves you or a neighbor. Immediate action can prevent a serious injury. Report the incident to your instructor who will help you decide if further treatment is necessary. 8. For reactions involving toxic or irritating vapors, use the fume hood. Test the hood for effective operation before beginning your work.
