redox Flashcards
what is redox chemistry about?
electron transfer and the ability for electrons to be transferred
define oxidation
loss of electrons
define reduction
gain of electrons
define static electricity
electrons from either substance have been displaced
what are redox reactions?
the combination of reduction and oxidation in the hopes of electron transfer
the species that undergoes oxidation is…
the reductant
the species that undergoes reduction is…
the oxidant
trends in electronegativity. what substance is most electronegative?
increases left to right and down to up. fluorine is most electronegative
defin electronegativity
ability to attract electrons
define strong oxidant
really wants to under go reduction
define strong reductant
really wants to undergo oxidation
the transfer of electrons is?
simultaneous and spontaneous
what determines if a redox reaction will occur?
downhill gradient
what does a half cell do?
host a redox half reaction
what happens when two half cells are joined?
a full redox reaction can occur
