10. Lab Safety
You must wear closed toe shoes, an apron and goggles to participate
Using 1.0 M HCl – if you spill, rinse under water in the sink
Place HCl into red graduated cylindder
Place H2O2 into yello/black graduated cylinder
Disposal
Place splints that have been burned into the designated container
Do not put the metals down the drain (place on paper towel)
Dispose liquid waste in the sink and sold waste in the trash
Rinse out all glassware and return to container

11. Lab Directions You will be working in pairs
Complete parts A,B and C only of the lab
Skip part D
Answer the Analysis and Conclusion questions for parts A-C
Skip the questions for part D
When you complete the lab, turn it in to Mr. Klotz

12. Exit Ticket - Reflection
What did I learn in lab today?
What errors did I make during the lab? How can I correct the errors in the future?
