Chemical Measurements

Every chemical measurement involves some uncertainty.

Uncertainty

  • E.g. a digital thermometer is able to measure to a precision of 0.1oC.
    • If this thermometer displayed a reading of 35.4oC, the actual temperature could be anywhere between 35.35oC and 35.45oC.

Reducing uncertainty

  • The larger the uncertainty, the larger the range of results you should expect.
  • This is a reason why it is important to repeat the measurements from experiments several times and calculate an average from them.
