    Study Notes

    Laboratory Instruments and Their Functions

    • Calorimeter: Used to measure heat changes during chemical reactions, including heat generated, transformed, or absorbed.
    • Conductivity Meter: A probe designed to assess an object's electrical conductance.
    • Triple Beam Balance: A balance equipped with three scales for precise measurement of mass.
    • Thermometer: An instrument for measuring the temperature of substances.
    • Pipette: A tool for transferring small, exact volumes of liquid between containers.
    • Electric Mass Balance: Designed to measure small masses accurately.

    Glassware Used in Measurements

    • Volumetric Flask: Essential for accurately measuring solution volumes when dissolving solids.
    • Beaker: Common glassware for mixing, heating, or cooling solutions, but not for precise volume measurement.
    • Graduated Cylinder: A tall, narrow measuring tool with marked graduations used for accurate liquid volume measurements.
    • Erlenmeyer Flask: Similar to a beaker but features a narrow neck to minimize splashing.

    Measurement Techniques and Practices

    • Taring Importance: Necessary to ensure only the substance’s mass is measured, excluding the container's weight.
    • Gas Volume Measurement: The volume of gas can be determined by knowing the volume of its container.
    • Accurate Liquid Measurement Tools: Graduated cylinders and volumetric flasks are the most accurate for measuring liquid volumes.

    Practice Readings

    • Graduated Cylinder Reading: Example measurement can be 6.6 mL, with emphasis on identifying the meniscus.
    • Triple Beam Balance Readings: Various example mass readings include:
      • 290.4 g
      • 57.3 g
      • 107.7 g
