LabSafety

Safety Rules

•  Safety goggles must be worn during labs at all times. Wear sensible clothing (confine long hair and fuzzy clothing) and enclosed shoes, particularly when doing chemistry labs.

Safety Rules

•  Know where our safety equipment is! If you need to use the eye wash, you must wash eyes for at least 15 minutes.

Safety Rules

Burners – keep in MIDDLE of table. NEVER point test tubes toward yourself or others. When heating test tubes, tilt it and heat gently and evenly. Use boiling chips when boiling liquids in a flask or beaker to prevent bumping.

Safety Rules Follow instructions carefully. Know the safety hazards of each experiment before starting. Do not perform unauthorized experiments. Only work in the laboratory when supervised by an instructor.

Safety Rules Keep tabletops clean. Return all equipment to its original location before leaving the lab. Clean all spills immediately.

Safety Rules Report all accidents, no matter how minor, to the instructor. If you break something made of glass, be sure to use dustpan and hand broom to sweep it up and dispose of it in the glass waste receptacle.

Safety Rules

Never return chemicals to bottles of their origin. If you have excess, give it to another student or throw it away. Check labels on containers twice to make sure you use the right chemical and of the correct concentration. Dispose of chemicals in proper receptacle.

Always add concentrated acids or bases to water, never water to concentrated acids or bases. Water holds more heat and if it splatters it is more dilute.

Use fume hoods when noxious fumes may be present in an experiment or use wafting.

ßwafting

Safety Rules Do not stick objects into bottle except spatula or dropper provided for that bottle. Do not set the spatula or dropper down on the counter (you may contaminate it). Keep each spatula or dropper with the proper bottle. Return the spatula or dropper to the tube attached to the bottle to avoid switching.

Safety Rules

In case of an emergency where we have to evacuate, proceed out the nearest exit and stand away from the building. In case of earthquake duck up against lab table and cover face.

Safety Rules

Never put anything in your mouth while in the lab (including chemicals, solutions, equipment, cigarettes, food, drink, or gum). Put all food and drinks in your bag.

Chapter 1 Introduction to Chemistry

What is Chemistry? •  Chemistry = study of the composition of

matter & the changes matter undergoes

So…What is Matter? •  Matter = anything that has mass and volume

(occupies space)

Chemistry •  Because living and nonliving things are made

of matter, chemistry affects all aspects of life and most natural events

Fields of Chemistry

Areas of Study The 5 traditional areas of study are: 1.  Inorganic chemistry 2.  Organic chemistry 3.  Biochemistry 4.  Analytical chemistry 5.  Physical chemistry

dopamine

Inorganic Chemistry •  Inorganic Chemistry =

Study of chemicals that generally do not contain carbon.

•  Inorganic chemicals are found mainly in non-living things, such as rocks.

Inorganic Chemistry

Organic Chemistry •  Organic chemistry = Study of all chemicals

containing C and H •  While it is true that organic compounds can contain

other elements, the bond between carbon and hydrogen is what makes a compound organic.

Organic Chemistry dopamine

Biochemistry •  Biochemistry = The study of the chemistry of living

organisms •  Biochemistry has become the foundation for

understanding all biological processes. It has provided explanations for the causes of many diseases in humans, animals, and plants.

Analytical Chemistry •  Analytical chemistry = Focuses on the composition

of matter to reveal its composition, structure, and extent.

•  It’s the science of determining what matter is and how much of it exists.

Physical Chemistry •  Physical chemistry = Blends chemistry and physics.

Involves the physical characteristics (properties) of molecules.

•  There are 3 branches: Thermodynamics (energetics of chemical rxns), quantum chemistry (structure of molecules), and chemical kinetics (rates of rxn).
