REDOX CHEMISTRY
ELECTROCHEMISTRY
"Redox" processes are chemical reactions that involve transfer of electrons
\ they are called electron
transfer reactions
• there is a change of oxidation number the
oxidant is reduced, reductant is oxidized
oxidant is reduced, reductant is oxidized
eg. O2 /O2- ox.no.
(0) / ox.no. (-2)
• an electrolyte must be involved as this
contains mobile charge carriers;
- generally it is a solution of ions or
a molten ionic material.
