  • Esterification Reaction and equilibrium constant determination.

    Esterification Reaction and equilibrium constant determination.

    Esterification is a common organic reaction that involves the reaction of a carboxylic acid with an alcohol to form an ester and water. In this experiment, we will be carrying out an esterification reaction to test the equilibrium position at different temperatures using ethanoic acid and ethanol. Safety precautions: • Wear personal protective equipment (PPE)…

  • The Winkler Method – Biological Oxygen Demand BOD

    The Winkler Method – Biological Oxygen Demand BOD

    The Winkler method is a widely used analytical technique for determining the amount of dissolved oxygen in water samples. Dissolved oxygen is essential for aquatic life and is an important indicator of water quality. The Winkler method involves the addition of reagents to a water sample that react with dissolved oxygen to produce a measurable…
