Involves the use of classical methods and the use of scientific instruments Fundamental Concepts on Analytical Chemistry Analytical Methods Classical Instrumental Methods Methods Rely on chemical Depend on the reactions to perform measurement of a an analysis; wet physical property of chemistry the analyte Can be divided into Uses an apparatus to qualitative (color, odor, measure physical etc.) and quantitative quantities such as light (gravimetry, volumetry, absorption, etc.) analyses fluorescence, etc Fundamental Concepts on Analytical Chemistry Analytical Methods – Classical Quantitaive Gravimetry: Moisture via gravimetry (usage of moisture analyzer/drying oven analyte signal is a method) measurement of mass Total dissolved solids/total soluble or change in mass solids (drying oven method) Volumetry: Determination of %Salt via Mohr Measurement of the volume of a solution whose concentration Titration is known and applied to determine the concentration of Titratable acidity via NaOH the analyte Titration Analytical Methods – Classical Quantitative Volumetry Indicator: added to the analyte to produce an observable physical change Titrant: reagent of known concentration added to analyte solution Analytical Methods – Classical Quantitative Volumetry – Definition of Terms Equivalence Point: Amount of titrant added is enough to completely neutralize analyte solution Endpoint: Point in titration when a physical change occurs; associated with chemical equivalence. Analytical Methods – Classical Quantitative Volumetry – Acid-Base Neutralization reaction between an acid and a base to form salt and water. e.g. Determination of Titratable Acid of Brine Solution Analytical Methods – Classical Quantitative Volumetry – Precipitation Titration Involves the formation of a precipitate (solids) during titration. e.g. Mohr titration for %Salt  Fundamental Concepts on Analytical Chemistry Analytical Methods – Instrumental i.

Top loading balances can be used for large magnitude and not so sensitive methods/analysis - Always use weighing containers e.g. beaker - Be mindful of temperature stability and vibrations around the area. Fundamental Concepts on Analytical Chemistry Laboratory Basics On Handling and Transferring of Liquids - Accuracy hierarchy: graduated cyclinder < measuring pipette < volumetric pipette < pipettor - On using glasswares for measuring liquid, be mindful of the meniscus. Observe with the glassware on eye level. LABORATORY SAFETY GOOD LABORATORY PRACTICES Improper Storage of Waste  Storage of waste in a fume hood where reactions are being carried out.  Leaving a funnel in the waste bottle.  A funnel can too easily be moved to an adjacent (incompatible) waste bottle and result in a fire or explosion. When you are done with it, cap it! LABORATORY SAFETY ACCIDENTS CAN HAPPEN TO ANYONE, ANY TIME, ANY WHERE.  LABORATORY SAFETY 32 Even if it is a day-to-day routine, RISKS REMAIN THE SAME. Recognize hazards, have preventive measures, & make emergency procedures. LABORATORY SAFETY TYPES OF HAZARDS CHEMICAL BIOLOGICAL PHYSICAL LABORATORY SAFETY TOP 5 LAB HAZARDS Fire/Explosion Skin Absorption of Chemicals Thermal and Chemical Burns Inhalation of Chemicals Cuts to the Skin LABORATORY SAFETY WORKING AREA LABORATORY SAFETY WORKING AREA clean and organized laboratory litter-free and non-slippery floors grounded electrical connections adequate illumination available spill kit, first aid box, emergency eye wash, emergency showers, emergency exit LABORATORY SAFETY FUME HOOD protects you from being exposed to chemical fumes, gases, and vapors that are generated within the enclosure fume hood is NOT a storage area use fume hood for all procedures that might result in the release of hazardous vapors or dust have an appropriate trap and make sure the setup is confined conduct all vacuum operations inside the fume hood LABORATORY SAFETY SPILLAGE immediately confine the area take note of the details of the incident do not clean up spills unless trained to do so wear protective gear when cleaning up spills supplies for cleaning should be in the kit (e.g., inert absorbent, plastic scoop, plastic bag, chemical-resistant gloves, and goggles LABORATORY SAFETY FIRST AID keep your first aid kit in a central location so it is easily accessible try to keep the contents of the first aid kit at room temperature if your first aid kit contains medications, remember to check expiration dates and replace when necessary usage must be well-documented and monitored LABORATORY SAFETY SHOWER & EYE WASH monthly routine check-up to ensure that emergency shower and eye wash are working properly shower requirements: - at least 30L/min water flow - must not shut off automatically - at least drinking water quality wash fountain requirements: - always cleaned - use sterile water LABORATORY SAFETY PERSONNEL Safety Procedures Wear apron or laboratory gown during the entire period of the laboratory work. Whenever anyone is working with chemicals or apparatus in the laboratory, safety goggles are required. Safety Procedures Do not dare touch a hot burner. Never throw a lighted match to the sink. Flammable solutions thrown at the sink may ignite fire. Flammable reagents like toluene, methanol, ethanol and many other organic compounds should be stored in closed containers and away from open flames.  Safety Procedures Avoid direct contact with chemicals: If you spill something, clean it up immediately before it dries or gets on your papers or skin. Any chemical spill on a person should be washed off immediately using safety shower. Any chemicals contacting one’s eyes should be immediately and thoroughly rinsed out using the safety wash.  Safety Procedures Never pipet by mouth. Many chemicals used in the laboratory are toxic. Never taste a chemical unless specifically directed to do so. Inhale odors and chemicals with great caution. Waft vapors toward your nose. Use the hood in performing experiments involving production of poisonous and irritating gases. Wash your hands thoroughly before leaving the laboratory to remove any potential chemical residues. Acids must be handled properly. If acids splash on the skin, wash the skin immediately with water and sodium carbonate solution, and then rinse again with plenty of water.  In diluting or mixing acids, always pour the acid slowly into the water while stirring. Do not reverse the process. So much heat may be liberated in the solution that steam may form with explosive violence. Safety Procedures Alkalis may damage the skin. Wash the skin with plenty of water and then with 1% acetic acid solution and rinse with plenty of water. Safety Procedures When heating a solution in a test tube, the mouth of the test tube should be away from the body. Do not point the test tube toward anybody. Safety Procedures Do not hold hot objects. Always use test tube holder or crucible tongs in handling hot dishes or apparatus. Always use a wire gauze, asbestos pad, or water bath in heating a container. Do not touch glass that has been near a flame or hot plate. Hot glass looks the same as cool glass and may cause serious burns. 46 HANDLING CHEMICALS Laboratory Safety CHEMICAL HANDLING & STORAGE ❑ always review SDS for proper storage conditions and procedures ❑ do not leave chemicals in the working area ❑ use “first in, first out” system ❑ regularly inspect stored chemicals for expiration, deterioration, and integrity ❑ do not overcrowd shelves ❑ storage cabinets should not be above shoulder height ❑ label storage cabinets according to chemical family or hazard classification LABORATORY SAFETY LABORATORY SAFETY LABORATORY SAFETY SAFETY DATA SHEET product identification composition hazards identification - emergency overview - potential health effects -potential environmental effects first aid measures accidental release measures handling and storage physical and chemical properties stability and reactivity proper disposal LABORATORY SAFETY EMERGENCY RESPONSE LABORATORY SAFETY EMERGENCY RESPONSE Do not panic. Familiarize the exit points in the laboratory Turn off all electrical equipment Orderly leave the building and gather at assembly point designated by the company Thank You!!!
