OCR Chemistry PAG 1.2 Simulation

Bring your chemistry lessons to life with this fully interactive, browser-based web simulation designed to model the classic gas collection practical. This resource allows students to safely and accurately explore stoichiometry, molar volume at RTP (24,000 cm3/mol, and quantitative analysis without the logistical hurdles of glassware breakage or chemical waste.Whether used for remote learning, front-of-class demonstrations, or individual student inquiry, this application provides an immersive laboratory experience right in the browser.

Key Features & Educational BenefitsRealistic Dynamic Visuals: Features an animated chemical balance, real-time effervescence (H2 gas evolution), a delivery tube system, and water displacement inside an inverted 250 cm3 graduated measuring cylinder. Variable Mass Control: Students can adjust the mass of the magnesium ribbon between 0.12 g and 0.16 g to investigate how limiting reagents affect the theoretical and captured gas volumes.
