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.

MolView is an intuitive, Open-Source web-application to make science and education more awesome! It allows students and teachers to visualise different molecules structures and examine their properties. MolView is connected to numerous databases publicly available to provide the required data such as PubChem, ChemSpider, ChEMBL, DrugBank, the Crystallography Open Database.
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.
