Study Notes
General Requirements
- Students must wear a laboratory gown, bring a laboratory manual, and maintain a laboratory notebook during each session.
- Pre-lab data entries must be completed in the laboratory notebook prior to class attendance.
- Non-compliance results in a grade of zero for the laboratory notebook, data, performance, and report.
Laboratory Housekeeping & Safety Rules
- Always wear a laboratory gown in the lab.
- Eating, drinking, loitering, and smoking in the laboratory are strictly prohibited.
- Only scheduled experiments may be performed; unauthorized experiments are forbidden.
- Familiarization with safety features, including fire extinguishers and emergency exits, is encouraged.
- Check requisitioned glassware and materials for cracks; report any defects immediately.
- Economically use reagents, water, and gas; avoid contamination of chemicals by using designated tools.
- Handle corrosive acids and caustic substances carefully; neutralize skin spills using sodium bicarbonate or dilute acetic acid and rinse with water.
- Add acid to water when preparing dilute acid solutions, never the reverse.
- Use a non-luminous flame for heating, keeping it no more than two inches high, and ensure gas is turned off when not in use.
- Allow heated objects to cool safely and protect hands when handling hot equipment.
- Report all accidents to the instructor, regardless of severity.

- Chairs should be placed on tables, and all utilities (lights, fans, water, and gas) should be turned off before exiting.
General Directions
- Read and understand the entire experiment before attending the lab, familiarizing with both theory and experimental parts.
- Know the reasoning behind each step, not just the directions.
- Develop observational and reasoning skills; bring textbooks for reference.
- Record observations contemporaneously to save time and enhance accuracy.
