Simple Titration – Acid/Base
Titration is a common laboratory technique used to determine the concentration of a substance in a solution. In this case, we will be performing a titration with sodium hydroxide (NaOH) and hydrochloric acid (HCl) to determine the concentration of HCl in a given solution.
Redox – Iron Tablet Titration (Improved)
Iron tablet titration is a common laboratory method used to determine the amount of iron present in a sample, such as an iron supplement tablet. This method involves reacting the iron in the tablet with a solution of potassium permanganate (KMnO4) to produce a purple colour. The endpoint of the titration is reached when the…
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 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…
