Reactivity Series – Reactions of Metals and Water (includes model data and conclusion)
Introduction: The reactivity of metals with water is an important topic in chemistry, as it helps us understand the behavior of metals and their potential uses in different applications. In this investigation, we will determine the order of reactivity of a series of metals with water. Materials and Methods: Materials: A series of metals (e.g., … Continue reading Reactivity Series – Reactions of Metals and Water (includes model data and conclusion)
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) … Continue reading Esterification Reaction and equilibrium constant determination.
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 … Continue reading The Winkler Method – Biological Oxygen Demand BOD
