Risks
Chemical Burns: Sodium hydroxide (NaOH), a strong base, can produce serious burns when it comes into contact with the skin or eyes. Always use protective gloves, goggles, and a lab coat when working with NaOH. In the event of contact, rinse thoroughly with lots of water and seek medical assistance as needed.
Inhalation of Fumes: Both acetic acid in vinegar and sodium hydroxide can emit fumes that can irritate the respiratory tract. Precaution: To reduce fume exposure, do the experiment in a well-ventilated environment or beneath a fumehood.
Spillage and Slips: Spilling NaOH or vinegar on the floor might provide a slippery surface and increase the danger of falling. Precaution: Clean up any spills promptly with suitable neutralising agents (e.g., vinegar for NaOH spills).
Glassware: Handling glassware, such as burettes and pipettes, can cause breakage, resulting in wounds or accidents. Precaution: Handle glassware with care, examine it for cracks before use, and dispose of broken glass appropriately in a designated receptacle.
Incorrect Chemical Disposal: Improper disposal of sodium hydroxide or acidic solutions can harm the environment and induce chemical reactions in waste systems. Precaution: Before disposal, neutralise the NaOH solution with a weak acid such as acetic acid, and adhere to local chemical waste disposal standards.
Skin Irritation from Acetic Acid: Although vinegar is typically harmless, strong acetic acid can cause skin irritation. Wear gloves when working with vinegar and avoid prolonged contact with the skin.
