Laboratory Safety and Equipment Quiz

Basic Safety Practices

• Always wear safety goggles, gloves, and lab coats to protect against chemical splashes.
• Know the location of safety equipment like eyewash stations, safety showers, and fire extinguishers.
• Avoid eating or drinking in the lab to prevent contamination and ingestion of hazardous materials.

Protocols in Borrowing Laboratory Materials

• Obtain permission before using or borrowing equipment from the lab.
• Return borrowed materials in the same condition they were received; report any damages.
• Keep track of borrowed items and their return deadlines to avoid fines or replacement costs.

Basic Apparatus & Equipment Functions

• Beakers: Used for mixing, stirring, and heating liquids; allows for easy measurement of liquid volume.
• Flasks:
  • Erlenmeyer Flask: Ideal for mixing and swirling liquids without risk of spillage due to its narrow neck.
  • Volumetric Flask: Designed for precise measurement and containing a specific volume of liquid.
• Pipettes: Instruments used for transferring precise volumes of liquids; available in various types, including graduated and volumetric pipettes.
• Graduated Cylinders: Used for measuring liquid volumes accurately; taller and narrower than beakers.
• Burettes: Essential for titrations; allows precise dispensing of liquid with a stopcock for control.
• Test Tubes: Used for holding, mixing, or heating small quantities of substances; benefit from being easily heated and cooled.

Chemical Formula Writing

• Understand basic principles of writing chemical formulas, including the use of symbols for elements and subscripts for the number of atoms.
• Follow the conventions of oxidation states when applicable to denote the charge of ions in compounds.

Naming and Balancing Chemical Reactions

• Use the IUPAC naming system for compounds, including prefixes for molecular compounds and suffixes indicating oxidation states.
• Balancing involves ensuring the number of atoms for each element is the same on both sides of the reaction equation, following the law of conservation of mass.
• Practice balancing through trial and error or using algebraic methods for more complex reactions.
