    Study Notes

    Identifying Solutions

    • Acids, bases, and salts can be found in common household and school items, including food, cleaning products, and laboratory substances.
    • Litmus indicators change color in response to pH levels:
      • Acids turn blue litmus paper red.
      • Bases turn red litmus paper blue.
      • Neutral solutions do not change the color of either litmus paper.
    • Common examples of acids include vinegar (acetic acid) and lemon juice (citric acid).
    • Common examples of bases include baking soda (sodium bicarbonate) and soap.
    • Common examples of salts include table salt (sodium chloride) and Epsom salt (magnesium sulfate).

    Use and Handling of Science Equipment

    • Proper use of science equipment ensures safety and accuracy during experiments.
    • Always wear appropriate personal protective equipment (PPE) such as gloves and goggles when handling chemicals.
    • Familiarize with basic lab equipment:
      • Test tubes and holders for mixing and observing reactions.
      • Beakers and flasks for measuring and storing liquids.
      • Bunsen burners for heating substances.
    • Understand the correct procedures for using indicators, such as adding a few drops of litmus to the solution to observe color changes.
    • Follow lab protocols for disposal of chemicals to prevent contamination or accidents.
