REDOX reactions Flashcards
redox reactions full name
reduction - oxidation recations
what is a redox reaction
a type of chemical reaction that involves a transfer of electrons between two species
oxidation
the loss of one or more electrons
reduction
the gain of one or more electrons
acronym to remeber oxidation/redduction
OIL RIG
OIL RIG meaning
oxidation is loss, reduction is gain
oxidant
a chemical that causes something else to undergo oxidation, but it itself is reduced
reductant
a chemical that causes something to undergo reduction, but it itself is oxidised
half equations
show either oxidation.reduction and electrons present in them
where are electrons in a reduction reaction
on the reactants side
where are electrons in an oxidation reaction
on the products side
how to identify half equations from full equations
we match up the elements from the reactant side with its partner on the products side
what is one technique used to identify redox reactions
the use of oxidation states
oxidation states
indicate that the charge that an atom may have as a result oof the movement of electrons during oxidation
a change iin oxidation states indicates that…
electrons have either been lost or gained and therefore a redox reaction has occured
