Electrochemistry is
Study of electron in atom
Study of electricity in molecules
The relationship between chemical reactions and electricity
the study of electrons moving from one a tom to another
An oxidizing agent will
increase in mass
lose electrons
be reduced
increase in oxidation number
The reaction 2NaCl → 2Na + Cl2 is an example of
a reduction reaction, only
both an oxidation and reduction reaction
an oxidation reaction, only
neither an oxidation nor a reduction reaction
Oxidation-reduction reactions occur because of the competition between particles for
electrons
positrons
protons
neutrons
Pb + 2Ag+ → Pb+2 + 2Ag
The chemical species being reduced is
Ag
Pb
Pb+2
Ag+
