Question

What is the key factor in defining a reaction as an oxidation-reduction reaction?



transfer of electrons between atoms



oxygen as one of the reactants



making and breaking ionic bonds



precipitation of solid from the reaction solution

Answer 1

Answer:

Transfer of electrons between atoms

Explanation:

Just because it has the prefix "oxi" it doesn't necessarily mean that oxygen exists as a reactant.

Making and breaking ionic compounds happen right before or after redox reactions after the atoms or ions are modified into one another.

precipitation occurs during the redox rxns involved in electrolysis & daniel cells. but it is not a key factor.
