Redox Electron Transfer — Interactive

Redox Electron Transfer

Reaction Pair

Oxidation loses e⁻

Zn → Zn²⁺ + 2e⁻

Reduction gains e⁻

Cu²⁺ + 2e⁻ → Cu

Overall equation

Zn(s) + Cu²⁺(aq) → Zn²⁺(aq) + Cu(s)

Blue circles = electrons · Arrows show electron flow from reductant to oxidant

OIL RIG — Oxidation Is Loss, Reduction Is Gain · electrons always flow from reductant to oxidant Interactive
