Titration – Redox Iron tablet
In this experiment, we explore the use of redox titration to determine the percentage by mass of iron (II) sulfate in iron tablets. By using potassium manganate in acidic solution, we can observe the permanent pink colour that indicates the end-point of the titration. With careful measurements and calculations, we can calculate the amount of…

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…

Quantitative Chemistry – calculating the percentage composition of iron in iron tablets.
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…
