Microscale, Maximum Impact: AL Chemistry Enthalpy Investigation! 

Our A-Level Chemistry (9701) students hit the lab to investigate the thermodynamics of displacement reactions using an ultra-efficient microscale calorimetry approach! 

By reacting excess zinc powder with varying concentrations of copper(II) sulfate (0.0 to 1.0 mol dm^-3), the class tested theoretical kinetics and thermodynamics in action:

Zn(s) + Cu^2+ (aq) → Zn^2+ (aq) + Cu(s)

Lab Highlights & Analytical Mastery:

Micro-Calorimetry Design: Students built custom cotton-wool lagged insulation systems to minimize heat loss while working with tiny 10.0 cm^3 solution volumes.

Precision Dilutions: Prepared serial dilutions across 5 reaction vials to track temperature changes (
