To create a supernaturated solution, a student heats a beaker of water on a hot plate and adds sugar until no more sugar will dissolve. The student then strains the solution through a funnel using filter paper and allows the solution to cool. Name two safety procedures the student should follow in this expirement, and explain why the safety procedures are necessary to prevent injury
In this experiment, there are two key safety procedures that the student should follow to prevent injury:
1. Proper use of heating equipment: The student should utilize the hot plate safely and responsibly. Here's why:
- Ensure proper use of the hot plate: The student should be aware of the correct operating procedures for the hot plate, such as setting the appropriate temperature, using the proper heating utensils, and avoiding any potential hazards associated with the equipment. This way, the risk of burns, fires, or electrical mishaps can be minimized.
- Proper handling of hot objects: Whenever the student is dealing with heated materials, it is essential to use appropriate protective equipment such as heat-resistant gloves or tongs to prevent burns. Furthermore, the student should be cautious while transferring hot beakers, avoiding splashes or spills that could cause harm.
2. Safe handling of chemicals: The student must take necessary precautions when working with chemicals. Here's why:
- Follow proper lab attire: The student should wear appropriate protective gear, including goggles, to protect their eyes from potential chemical splashes or fumes. Wearing a lab coat or an apron can also prevent clothing from coming into contact with chemicals or getting stained.
- Be cautious about chemicals' properties: Certain chemicals may pose health risks or react violently if mishandled. Sugar itself is a relatively low-risk substance, but other chemicals used in experiments might demand specific safety measures. The student should always be aware of any potential hazards associated with the substances they are working with and take appropriate measures to ensure their safety.
By following these safety procedures, the student can minimize the risk of injury or accidents while conducting the experiment. It is crucial to prioritize safety in any laboratory setting to safeguard the well-being of both students and researchers.
