1. 1 Goggles To enter the general chemistry lab, you need: Closed-toe shoes Lab manual

2. 2 Experiment 1 LABORATORY TOOLS: THE BALANCE, GRADUATED CYLINDER, BURET, AND BUNSEN BURNER To have direct experience using these equipments. To develop basic skills in making measurements. To learn much more than the operational aspects of these devices. To learn how to record data as it is observed.

3. 3 Digital Balance Do not place heavy item(s) (heavier than the balance can measure) on the balances. Zero the balance using the tare (zero) function. Read the number till it is fixed/stable.

4. 4 Graduate Cylinder

5. 5 Buret

6. 6 Bunsen Burner Air control Gas inlet Gas control Hottest part of the flame is just above the inner cone.

7. 7 Procedure Follow the directions on the report sheet. Record data and illustrate necessary calculations in the space provided below each directive. Clearly label data and include units. Record all displayed digits on the electronic balance. Use the same balance for all weights in an experiment. Read and record liquid levels in the burettes to the hundredths place (estimated digit). Some beakers will be used more than once. If necessary, rinse and dry them between uses. Answer questions as you go along. Tear and submit the Work Sheets before you leave the lab.

8. 8 Clean up and Disposal Discard the solid salt in a nearby sink or trash can. Double check gas to Bunsen burner; make sure it is off. Clean all glassware that you used with soap and water; give it a final rinse with deionized water. Empty your wash bottle, and return it and all other equipment to your drawer. Lock the drawer. Clean your work area with a sponge/paper towel.
