In this investigation, you will measure the enthalpy of neutralisation (ΔHₙₑᵤₜ) for a strong acid and a weak acid reacting with a strong base, and use the difference to explore the relationship between enthalpy change and acid dissociation constants (Kₐ and pKₐ). This practical is suitable for IB Diploma Chemistry HL and makes an excellent Internal Assessment (IA) topic.
The iodine clock reaction is a classic chemistry experiment that produces a dramatic, sudden colour change from colourless to deep blue-black. In this investigation, you will explore how changing the temperature affects the rate of this reaction and use your results to determine the activation energy of the reaction.
This chemistry practical aims to determine the value of x in Fe(NH4)2(SO4)2.xH2O through titration with potassium manganate (VII). The experiment involves mixing ammonium iron(II) sulfate with dilute sulfuric acid and titrating until the endpoint is reached. Results facilitate calculations of water of crystallization in the compound.
