1. SOME LABORATORY TOOL

2. Beaker Definition: A wide, cylindrical container used to mix, heat, or hold liquids. Example: Used to mix vinegar and baking soda during a chemical reaction experiment.

3. Reagent Bottle Definition: A container used to store chemicals or solutions. Example: Holds hydrochloric acid used in a titration.

4. Bunsen Burner Definition: A small gas burner used to heat substances in the lab. Example: Heats a test tube containing water to observe boiling.

5. Burette Definition: A long, graduated tube used to dispense precise amounts of liquid, especially in titrations. Example: Used to slowly add sodium hydroxide to an acid during a titration to find the neutralization point.

6. Erlenmeyer Flask Definition: A flask with a narrow neck and wide base, used for mixing and heating liquids. Example: Used to swirl and mix chemicals without spilling, like in a reaction between zinc and hydrochloric acid.

7. Evaporating Dish Definition: A shallow dish used to heat liquids so they evaporate, leaving solids behind. Example: Used to evaporate water from a salt solution to collect the salt crystals.

8. Florence Flask Definition: A round-bottom flask used for boiling liquids evenly. Example: Used to boil liquids evenly, such as in distillation experiments.

9. Funnel Definition: A tool used to pour liquids or powders into containers with small openings. Example: Used to pour a liquid into a narrow-necked bottle without spilling.

10. Micro Spatula Definition: A small tool used to transfer tiny amounts of solid chemicals. Example: Used to transfer a small amount of copper sulfate powder to a beaker.

11. Mortar and Pestle Definition: A set used to grind solid substances into powder. Example: Used to grind solid sugar crystals into powder for easier dissolution.

12. Pipette Definition: A tool used to measure and transfer small amounts of liquid. Example: Used to measure and transfer 5 mL of a chemical solution precisely.

13. Ring Stand Definition: A stand used to hold lab equipment like clamps and rings during experiments. Example: Holds a beaker above a Bunsen burner using a ring and wire gauze.

14. Test Tube Holder Definition: A clamp used to hold test tubes, especially when hot. Example: Used to hold a test tube over a flame to heat a substance.

15. Test Tube Rack Definition: A stand used to hold multiple test tubes upright. Example: Holds multiple test tubes upright during a chemical reaction observation.

16. Thermometer Definition: A device used to measure temperature. Example: Measures the temperature of water being heated in a beaker.

17. Tongs Definition: A tool used to hold or move hot equipment or substances. Example: Used to safely move a hot crucible from the flame to a cooling area.

18. Volumetric Flask Definition: A flask used to prepare solutions of precise volumes. Example: Used to prepare exactly 250 mL of a standard sodium chloride solution.

19. Barometer Definition: An instrument used to measure atmospheric pressure. Example: Used to measure atmospheric pressure in a weather station experiment.
