Cards

  1. 1Laboratory glassware
    Various forms of glass equipment used in chemistry labs for conducting experiments, measurements, and reactions
  2. 2Is glassware central to all chemistry?
    No, while stereotypically associated with chemistry, much experimental and industrial chemistry is done without glassware
  3. 3Reagent bottle
    A container used to store and dispense chemical substances (reagents) in the laboratory
  4. 4Ammonium hydroxide
    An aqueous solution of ammonia (NH₃), commonly stored in reagent bottles in laboratories
  5. 5Nitric acid
    A highly corrosive strong acid (HNO₃) used in various chemical reactions and stored in specialized containers
  6. 6Chemical solution
    A homogeneous mixture of two or more substances, typically a solute dissolved in a solvent
  7. 7Spectroscopy
    A technique used to analyze substances by measuring the interaction between matter and electromagnetic radiation
  8. 8Chromatography
    A laboratory technique for separating mixtures into individual components based on their different properties
  9. 9Main tools of chemical analysis
    Spectroscopy and chromatography are primary analytical tools for identifying and separating chemical substances
  10. 10Infrared spectroscopy (IR)
    A technique that analyzes molecular vibrations by measuring absorption of infrared light, providing structural information
  11. 11Nuclear magnetic resonance (NMR) spectroscopy
    A technique that detects magnetic properties of atomic nuclei to determine molecular structure and atom connectivity
  12. 12Mass spectrometry
    A technique that measures the mass-to-charge ratio of molecules to determine molecular weight and structure
  13. 13Crystallography
    The study of crystal structure and arrangement of atoms, useful for determining molecular geometry when single crystals are available
  14. 14Distillation
    A traditional separation method that uses differences in boiling points to separate liquid mixtures
  15. 15Crystallization
    A separation technique where dissolved substances form crystals as the solution becomes saturated or temperature changes
  16. 16Evaporation in chemistry
    The process of converting a liquid into vapor, often used to concentrate solutions or separate volatile components
  17. 17Solvent extraction
    A separation technique that uses immiscible solvents to selectively dissolve and separate components of a mixture
  18. 18What safety consideration is important for heating glassware?
    Use appropriate heat sources and ensure glassware is heat-resistant; some glass can crack under rapid temperature changes
  19. 19Why is proper labeling important in the lab?
    To prevent confusion, ensure correct substance identification, and maintain safety by knowing chemical hazards
  20. 20Fume hood
    A ventilated enclosure that protects lab workers from inhaling toxic fumes, vapors, or dust during experiments
  21. 21What should you do before mixing chemicals?
    Check compatibility, understand the reaction, wear appropriate PPE, and ensure proper ventilation
  22. 22Personal protective equipment (PPE) in chemistry
    Safety gear including lab coats, goggles, gloves, and sometimes face shields to protect from chemical hazards
  23. 23Why are safety goggles important in the lab?
    They protect eyes from chemical splashes, flying debris, and harmful vapors that could cause serious injury
  24. 24Purpose of a lab coat
    To protect skin and clothing from chemical splashes, spills, and contamination
  25. 25What type of gloves are commonly used in chemistry labs?
    Nitrile, latex, or neoprene gloves depending on the chemicals being handled and required resistance
  26. 26Safety shower
    An emergency fixture that provides a quick drench to wash off hazardous chemicals in case of large spills on the body
  27. 27Eyewash station
    An emergency device that delivers a stream of water to rinse chemicals from the eyes
  28. 28What should you do if chemicals splash in your eyes?
    Immediately use the eyewash station, rinse for at least 15 minutes, and seek medical attention
  29. 29How should you handle corrosive acids like nitric acid?
    Use in a fume hood, wear acid-resistant gloves and goggles, add acid to water (never reverse), and have neutralizing agents ready
  30. 30'add acid to water'
    When diluting acids, always add the acid slowly to water to control the exothermic reaction and prevent splashing
