Final answer:
The three most critical pieces of information on a chemical container label are the chemical name, any hazard warnings, and the concentration, which provide essential identification, safety, and usage details.
Step-by-step explanation:
When reading a chemical container label, three of the most important pieces of information that should be prioritized are the chemical name, any hazard warnings, and the concentration of the chemical. The chemical name is essential for identification and ensuring you are working with the correct substance. Hazard warnings, often represented by the Hazard Diamond or fire diamond, provide critical safety information about the risks associated with the chemical, including flammability, reactivity, and health risks. The concentration indicates the strength of the chemical and is necessary for proper dilution, usage, and storage.
Knowing these details is important for safety in a laboratory setting and for environmental protection, as some chemicals require specific disposal methods to prevent harm to people and the environment. It's always wise to reference the safety data sheets available for chemicals to ensure thorough understanding of safety precautions and handling instructions.
