Redox Reactions

A collection of flashcards covering key terms and concepts related to redox reactions.

Redox Reactions

Reactions that involve the transfer of electrons, where one reactant is oxidized and another is reduced.

Oxidation

The loss of electrons by a reactant in a redox reaction.

Reduction

The gain of electrons by a reactant in a redox reaction.

OIL RIG

A mnemonic to remember that 'Oxidation Is Loss' and 'Reduction Is Gain' of electrons.

Synthesis Reaction

A type of reaction where two or more reactants combine to form a single product.

Single Displacement Reaction

A type of reaction where one element displaces another in a compound.

Sample Redox Reaction

The reaction of magnesium with oxygen to form magnesium oxide: 2Mg(s) + O2(g) → 2MgO(s).

Silver Bromide Decomposition

A redox reaction where silver bromide decomposes into silver metal and bromine vapour: 2AgBr(s) → 2Ag(s) + Br2(g).

Electrolysis of Sodium Chloride

A process that produces sodium and chlorine gas by passing an electric current through molten sodium chloride.

Oxidation (Modern Definition)

Defined as the transfer of electrons from a reactant.

Not a Redox Reaction

The decomposition of calcium carbonate (CaCO3) does not involve electron transfer, thus it is not a redox reaction.
