Unformatted text preview: Chapter 18 Electrochemistry Tro, Chemistry: A Molecular Approach 2 Redox Reaction one or more elements change oxidation number all single displacement, and combustion, some synthesis and decomposition always have both oxidation and reduction split reaction into oxidation half-reaction and a reduction half-reaction aka electron transfer reactions half-reactions include electrons oxidizing agent is reactant molecule that causes oxidation contains element reduced reducing agent is reactant molecule that causes reduction contains the element oxidized Tro, Chemistry: A Molecular Approach 3 Oxidation & Reduction oxidation is the process that occurs when oxidation number of an element increases element loses electrons compound adds oxygen compound loses hydrogen half-reaction has electrons as products reduction is the process that occurs when oxidation number of an element decreases element gains electrons compound loses oxygen compound gains hydrogen Tro, Chemistry: A Molecular...
