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.
Investigate the reactivity series by reacting metals with dilute hydrochloric acid. IGCSE and GCSE chemistry practical with method, observations and conclusions.
Test the effect of light and CO2 on photosynthesis using the leaf starch test. IGCSE and IB biology prescribed practical with full method and analysis.
Investigate the effect of concentration on reaction rate using the iodine clock reaction. IB and A-level chemistry practical with method and kinetics analysis.
Chemistry exam practice questions on moles and concentration calculations. Worked examples covering molarity, titrations and stoichiometry for IB and IGCSE.
Test a leaf for starch to demonstrate photosynthesis. Step-by-step destarching, iodine test method and results for IGCSE and IB biology practical work.
