electrolytic cells use an external power supply to force a non spontaneous redox
start by looking at two half reactions and the overall redox reaction we get by
reduction of chlorine on the table to get the oxidation of chloride ions
next we'll add the half reaction for the reduction of zinc ions the way it is on
we'll add these two half reactions to get the overall redox equation
by the chloride ions therefore electrons can be cancelled before adding the two
and on the right side we have set and solid plus co2 gas
one . 36 volts and negative points 7 6 volts
redox reaction is a non-spontaneous reaction as written
we would not get solid zinc and chlorine gas
electrolysis uses an external power supply or battery to force a non
type of electrolytic cell this is what we call a type-1 electrolytic cell will
then we add a direct current power supply and wires
simplified symbols will represent a few protons x plus signs and a few electrons
when we close the switch and connect the power supply it takes electrons from the
electrode attached to the negative terminal
and the electrode on the right now has an excess of electrons giving it a net
and an electrolytic cell the electrode attached to the positive terminal of the
and the electrode attached to the negative terminal of the power supply is
cell
we'll add some molten zinc chloride to the container
around emotion
negative chloride ions will be attracted to the positive analed
the zinc iron will gain two electrons from the cathode
zinc solid
