Definition of Half-equations and electron transfer
Check what you remember
Read the wording for your board, then hide it and explain Half-equations and electron transfer in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
One electron is transferred per iron ion, so the half-equation Fe²⁺ → Fe³⁺ + e⁻ and the reverse reduction half-equation are written and balanced for charge and atoms before combining them.
