We are nearing the completion of stoichiometry, a foundational skill that directly supports Structure 1 (mole concept, empirical/molecular formulas) and Reactivity 2.1 (reacting quantities, limiting reactants). Beyond these, stoichiometric principles underpin numerous topics across the IBDP Chemistry syllabus — from equilibrium calculations to electrochemistry — making a strong grasp essential for efficient progression.
This week, students were introduced to:
- Preparing standardized solutions (accurate dilution, use of volumetric flasks)
- Solution stoichiometry: calculations involving concentration (mol dm⁻³) and volume
- Mole ratios in titration: applying balanced equations to acid-base and redox neutralizations
Next week, we will conclude with:
- Gas laws (Boyle, Charles, Avogadro, Combined)
- Ideal gas equation (PV = nRT) and its stoichiometric applications
This will complete Structure 1 and Reactivity 2.1 in preparation for a comprehensive end-of-Semester 1 assessment coming in 2 weeks time.
Students are strongly encouraged to:
- Complete all worksheets provided.
- Review shared slides and worked examples.
- Use Kognity for interactive practice and self-assessment.
Mastery now = confidence later. Keep up the great effort!
