1. Inorganic Chemistry Laboratory (CHEM242) Prof. Peter Khalifah Spring, 2007

2. TA’s for this class Lab supervisor (room 301):Don Taylor Adrienne Carver(Knapp group) Khadine Higgins(Maroney group) Office hours: TBA SelfMon, 3:30(After this lecture) Adrienne: Tue, 1:30(Avoids Organic overlap) KhadineTBA

3. Topics Congratulations on starting advanced chemistry training Will give you the respect of an independent researcher Will hold you to the responsibilities of an independent researcher

4. Respect Work with research-grade instruments Work with a wider range of elements Work with more expensive reagents Allow you to work with dangerous / toxic substances Work with labs that require skill / focus for success Teach the skills used for scientific research

5. Responsibility #1 = Safety Anticipate hazards (and responses) –MSDS sheets for chemicals, common sense for others Vision – high vulnerability –Safety glass are worn always in lab –Contacts are never worn in lab A clean lab is a safe lab –Clean up spills (powder or liquid) ASAP –Wash hands when leaving lab –Be aware of leaks (especially in troughs) Are you allergic to Latex?

6. Short list for safety Do not enter lab unless a TA / instructor is present Use common sense. Anticipate hazards. If in doubt, ask! Maintain a safe working environment –Clean up chemical and liquid spills immediately Avoid contact with chemicals (gloves always available) Safety goggles must be worn always, contacts never Open-toed shoes (sandals, etc.) are forbidden, long pants should be worn Food and drink must be left outside of lab Hair and clothing must be safe (avoid flames, chains, exposed midriffs) No work will be allowed unless these conditions are met!

7. General procedure for lab Before day of lab –Download and print experimental procedure (EP) –Write up pre-lab materials Day of lab –Show up on time (ie early!) –Bring EP, pre-lab, notebook, goggles –Have TA sign off on pre-lab –Brief introductory lecture –Perform experiments, record data in notebook –Have TA sign off on notebook, bench cleanliness One week later –Turn in lab report to TAs before class (notebook pages, typed work) –One week turn-around in grading

8. Homework assignment for next Monday Visit the web site of an inorganic journal –Inorganic Chemistry (ACS) –Dalton Transactions (Royal Society of Chemistry) Scan through 10 consecutive articles from the time period that you are assigned (Jan) Print out best written article among those, read it in detail, and bring it to class Mon.

9. Journal survey Out of the 10 articles skimmed, how many: Involved the synthesis of a molecule ____ Involved the synthesis of a non-molecular compound ____ Were entirely theoretical in nature ____ Involved a measurement (ie not just synthesis) ____ Utilized an advanced characterization technique new for you ____ Were well written ____ Were poorly written ____ Name: ____________________________ Lab Day ______
