Investigation for the reactivity of metals by observing single displacement reactions using different metal solutions and test metals.
Chromatography
Chromatography is a highly effective separation technique that can separate the components of a mixture based on their physical and chemical properties. To carry out a simple chromatography experiment, you will need chromatography paper, a pencil, ruler, mixture to be separated, solvent, glass jar or beaker, and paper clip or tape. The procedure involves drawing a line, applying a small spot of the mixture, placing the paper in a glass jar, waiting for the solvent to separate the components of the mixture, removing the paper and letting it dry, and visualizing the separated components. By carefully selecting the solvent and the chromatography paper, you can achieve a successful experiment and separate and identify the individual components of a mixture.

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.
Iron Tablet Titration: Step-by-Step Guide
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 purple colour disappears, indicating that all of the iron in the tablet has reacted with the KMnO4.
