1. Experiment to investigate the rate of effusion and the effect of molecular mass on effusion rate, planning steps, and the relationship between molecular mass and molecular speed, using iodine and propanone as reagents.
2. Titration methods for measuring the rate of reaction between iodine and propanone, calculation of molar concentrations, reaction time analysis, and rate calculation.
3. Qualitative analysis of acid reactions with various cations, identification of ions in unknown solutions based on solubility and precipitation reactions, including reactions with sodium hydroxide and ammonia.
4. Organic synthesis and analysis of compounds, reactions involving alkyl halides, functional group identification using reagents like sodium borohydride and Fehling’s solution.
5. Use of stoichiometry in determining reaction yields, calculation of error and adjustments to experimental methods for accurate results in organic reactions.
