In chemistry, balancing equations is crucial to understanding the stoichiometry of a reaction. In this experiment, you will learn how to balance the equation for the reaction between sodium thiosulphate and iodine using titration with starch indicator. By determining the stoichiometric coefficients, you can gain insight into the reactants and products involved in the chemical equation. This experiment provides a great opportunity to improve your titration skills and interpretation of results.
In this experiment, we aim to determine the concentration of a solution of sodium hydroxide by titration against a standard solution of potassium hydrogen phthalate. We will use phenolphthalein as an indicator to show when the reaction is complete. To perform the titration, we will need a burette, pipette, conical flask, sodium hydroxide solution, and potassium hydrogen phthalate solution, among other requirements. We will also need to ensure accuracy by recording burette readings to the nearest 0.05 cm3 and repeating titrations until they agree within 0.10 cm3. Finally, we will analyze the effects of various errors on the calculated value of the concentration of sodium hydroxide and discuss the reasons for using a colourless to pink solution for titration.
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 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.
