Final answer:
To mix chemicals safely, add acid to water, not vice versa, follow instructions exactly, and check safety data for each chemical. Always handle flammable chemicals cautiously, use personal protection, and dispose of chemicals properly. Alert your teacher immediately in case of any accidents.
Step-by-step explanation:
When mixing (cutting) chemicals, several important safety guidelines must be followed to prevent accidents and chemical injuries. Firstly, it's crucial to never add water to acid; instead, always add the acid to water to prevent exothermic reactions that can cause splashing and burns. Additionally, ensure to follow instructions carefully, including handling flammable chemicals with care, avoiding direct heat unless specified, and never tasting or touching chemicals. All steps and procedures provided by your teacher or in the experimental guide should be followed in the exact order to avoid unexpected reactions.
Always check safety data for any chemicals you're going to use and understand how to handle them before beginning your work. Utilize personal protective equipment as required and work in a well-ventilated area or fume hood if the chemicals produce harmful vapors. Upon completion, ensure proper disposal of chemicals as directed, and never leave Bunsen burners on or unattended.
In case of an accident, alert your teacher immediately, and remember to be alert and careful throughout your work with chemicals, hot glassware, and other laboratory equipment.
