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.
Determine the number of moles of water of crystallisation in hydrated copper(II) sulfate by heating to constant mass. Classic IB, A-level and GCSE chemistry practical with full method, safety notes and calculations.
Investigate the acid-base properties of Period 3 oxides from sodium to sulfur. IB and A-level chemistry practical with pH measurements and full analysis.
Explore aluminium's amphoteric nature by converting scrap aluminium into aluminium sulfate. A-level and IB chemistry practical with step-by-step method.
Observe and understand changes in states of matter by heating and cooling water. IGCSE and KS3 prescribed practical with method, safety notes and discussion.
