Redox
Question | Answer |
---|---|
electron transfer | loss or gain of electrons between atoms / ions |
half equation | Electrons are being lost or electrons are being gained : any redox reaction is made up of two half-reactions |
oxidation number | oxidation state; sort of electronic book-keeping system to help work out what has been oxidised or reduced |
oxidation | loss of electrons; an increase in oxidation number |
oxidising agent | a substance that oxidises another substance; an oxidant; substance that removes electrons from other species; it gets reduced |
redox reactions | electron transfer reactions are also known as oxidation–reduction reactions |
reducing agent | a substance that reduces another substance; a reductant; substance that donates electrons to other species; it gets oxidised |
reduction | gain of electrons; a decrease in oxidation number |
