Study Notes
General Chemistry Lab - Basic Laboratory Techniques
- The course is A0111302
- The instructor is Aya Khalaf
- The course is in the Faculty of Arts & Sciences, Allied Sciences department.
- The module covers basic laboratory techniques and safety procedures in a chemistry lab.
Safety Rules
- Know locations of safety equipment (showers, eyewashes, fire extinguishers) and emergency exits.
- Avoid contact with chemicals. Minimize chemical exposures.
- No horseplay is allowed.
- Assume all unknown chemicals are highly toxic.
- Post warning signs for unusual hazards, hazardous materials, and equipment.
- Avoid distracting other lab personnel.
- Use equipment correctly and for its intended purpose.
- Add acid to water, not water to acid.
- Avoid adding solids to hot liquids.
- Emphasize safety and chemical hygiene.
- Keep containers closed and clearly labeled.
- Do not taste or sniff chemicals.
- Do not eat, drink, or apply cosmetics where hazardous chemicals are used.
- Do not use mouth suction for pipetting.
- Wash exposed skin before leaving.
- Secure loose clothing and hair.
- Wear safety glasses or goggles when working with chemicals.
Safety Equipment
- Safety Shower: Used to wash off chemical spills.
- Eye Washer: Used to flush chemicals out of the eyes.
- Fire Extinguisher: Used to extinguish small fires.
- Fire Blanket: Used to smother small fires.
- Fume Hood: Used to contain hazardous fumes.
- First Aid: Provides immediate care for injuries.
Safety Precautions
- Determine potential hazards and take safety precautions before any work begins.
- Do not pour chemicals down the drain; use designated waste disposal containers.
- Keep sink traps filled with running water to prevent chemical buildup.
- Perform hazardous tasks in properly functioning fume hoods.
- Avoid working alone in a hazardous lab.
- Employees need access to related safety manuals and protocols.
- Limit access to labs and support areas to authorized personnel.
- Equipments should undergo regular inspections and maintenance.
- Designate proper waste storage locations.
- Avoid cell phone or earplug usage during experimental work.
- Do not use synthetic fiber clothing when working with flammable substances.
- Avoid wearing jewelry.
Chemical Observations
- Weighing: Uses an analytical balance (with accuracy standards).
- Measuring Liquids: Uses graduated cylinders, burettes, pipettes, volumetric flasks, and beakers
- Temperature: Uses thermometers.
Volume measurements
- SI unit for volume is m^3
- Volume of liquids are measured with measuring cylinders
- Pay attention to the meniscus while reading the volume.
Bunsen Burner
- Blue flame (high temperature, sufficient oxygen, non-luminous).
- Yellow flame (low temperature, insufficient oxygen, luminous).
- Adjust gas supply to achieve desired flame. (open/close air hole)
Lab Equipment
- The presentation lists a variety of glassware and equipment commonly found in a chemistry laboratory.
Report
- Data and calculations are on page 13
- Questions are on page 16 (including various question types, e.g. identifying types of glassware, defining flames etc.)
