Laboratory Techniques Quiz Answers And Explanations
1. B – A balance measures the mass of substances accurately, which is essential for chemical experiments.
2. B – A thermometer measures temperature and is crucial for monitoring reactions and ensuring safety.
3. B – Filtration separates insoluble solids from liquids using filter paper, leaving clear filtrate.
4. B – Distillation separates liquids based on boiling points; useful in purifying water or alcohol.
5. B – Evaporation removes the solvent, leaving behind dissolved solids, such as salt from saltwater.
6. B – Pipettes allow accurate transfer of specific volumes, which is important in titrations and precise experiments.
7. B – Burettes measure and deliver liquids accurately during titrations, ensuring precise chemical reactions.
8. A – Crucibles withstand very high temperatures for heating substances that cannot be heated in normal containers.
9. B – Beakers are versatile for mixing, heating, or storing liquids but are not for precise volume measurements.
10. B – Conical flasks allow mixing or titration with reduced risk of spillage due to their narrow neck.
