Sulfite Nanoparticle Oxygen Scavenging

Sulfite ions (SO₃²⁻) are one of the oldest antioxidant/preservative chemistries on earth — the reason wine, dried fruit and cured meat resist browning and spoilage in storage. This simulator renders a batch of sulfite nanoparticles inside a solution volume, along with dissolved oxygen molecules random-walking in from a permeable headspace and a set of sensitive target compounds (pigments, vitamins, fats) that spoil if oxygen reaches them unopposed. Every collision is resolved against the real chemistry: an Arrhenius-law reaction rate governs whether an oxygen molecule that reaches an active nanoparticle actually reacts and is consumed, and a temperature-dependent diffusion coefficient (Stokes–Einstein, scaled by water's viscosity) governs how fast the molecules random-walk through the volume. Push the dose, temperature and oxygen-influx sliders and watch the protective effect run out in real time as nanoparticles are consumed and turn from reactive green to spent grey.
