1. Experimental determination of the relative atomic mass of magnesium through titration and thermal decomposition methods.
2. Quantitative analysis involving titration calculations, mole determinations, and stoichiometric relationships for reactions of Mg and HCl.
3. Observations and inferences from qualitative analysis for cation and anion identification, including specific reagent interactions.
4. Procedures and calculations to verify complete dehydration of MgSO₄·7H₂O, with improvements for accuracy.
5. Gas evolution tests and identification based on standard chemical reactions, including practical observations for salt analysis.
6. Application of standard qualitative tests for common ions (e.g., sulfate, chloride, and carbonate) with expected precipitate behaviors.
